EU Vehicle Lighting Regulations: Approval, Installation and Marking
EU vehicle lighting regulations decide which lamps a road vehicle must carry, where they sit, what colour they show and how each lamp proves that it complies. Almost all of the technical content comes from UN Regulations under the 1958 Agreement, which the EU makes binding through its own type-approval law.
For a procurement officer or integrator the practical questions are narrower: which document governs the vehicle, which governs the lamp, what the mark on the lens means, and whether any of it applies to a military platform. This guide answers them in that order.
How the EU Framework Fits Together
EU lighting law is not one document. It is three layers, and most compliance questions become simple once it is clear which layer a requirement sits in.
The EU once wrote its own lighting directives, such as Directive 76/756/EEC on installation. Regulation (EC) No 661/2009 repealed those directives with effect from 1 November 2014 and replaced them with the equivalent UN Regulations. That is why almost every road lamp sold in Europe today carries a UN approval mark rather than an EU one, and why a lamp approved in one Member State is accepted in all the others.
Vehicle Type Approval Under Regulation (EU) 2018/858
Regulation (EU) 2018/858 lays down the administrative provisions and technical requirements for the type approval of motor vehicles of categories M and N, their trailers of category O, and the systems, components and separate technical units intended for them. It has applied since 1 September 2020, when it replaced Directive 2007/46/EC.
Article 5 requires vehicles and components to comply with the regulatory acts listed in Annex II. For lighting, those acts are UN Regulations named in Annex I to Regulation (EU) 2019/2144, the General Safety Regulation, which has applied since 6 July 2022. They include UN Regulation No 48 for installation, the lamp regulations covered below, and UN Regulation No 10 for electromagnetic compatibility.
Approval works at two levels, and buyers should keep them apart. The lamp is approved as a device, which proves it emits the right light. The vehicle is approved for the installation, which proves the right lamps are fitted in the right places. A lamp supplier cannot give a vehicle approval, and a vehicle cannot be approved with lamps that lack their own.
Article 38 requires manufacturers of components and separate technical units to mark each unit with its type-approval mark, and only marked units may be placed on the market. This is why an aftermarket or replacement lamp sold for road use in the EU must carry its approval mark. An unmarked lamp, however well made, is not a road-legal replacement.
Installation Rules: Where Lamps Go and How Many
UN Regulation No 48 covers the installation of lighting and light-signalling devices on vehicles of categories M, N and O. For each function it states whether the lamp is mandatory, optional or prohibited, how many are fitted, where they sit, the angles over which they must be visible, their colour and how they are switched. The EU publishes the text it applies in the Official Journal; the current publication, OJ reference 2021/1718, incorporates Supplement 1 to the 07 series of amendments.
| Function | Presence | Number |
|---|---|---|
| Main-beam headlamp | Mandatory on motor vehicles, prohibited on trailers | Two or four |
| Dipped-beam headlamp | Mandatory on motor vehicles, prohibited on trailers | Two |
| Front fog lamp | Optional on motor vehicles, prohibited on trailers | Two |
| Reversing lamp | Mandatory on motor vehicles and on O2, O3 and O4 trailers, optional on O1 | One, plus an optional second on M1 and on vehicles up to 6,000 mm long; two, plus two optional, on longer vehicles other than M1 |
| Direction indicators | Mandatory | According to the arrangement |
| Rear position lamp | Mandatory | Two |
| Rear fog lamp | Mandatory | One or two |
| Daytime running lamp | Mandatory on motor vehicles, prohibited on trailers | Two |
Colour is fixed per function: white for headlamps, front position, reversing and daytime running lamps; red for rear position, stop and rear fog lamps; amber for direction indicators. The reason is recognition. A driver reads the colour before the shape, so a red lamp means the rear of a vehicle and an amber flash means a change of direction anywhere in Europe.
Dipped-beam aim. R48 sets how far the dipped-beam cut-off must point downwards. For headlamps mounted below 1.0 m, the initial aim is 1.0 to 1.5 per cent downward; above 1.0 m it is 1.5 to 2.0 per cent, within wider limits that must hold under every load condition. On a military or specialist vehicle this matters more than on a car: headlamps sit high, and armour kits, stowage and payload change the pitch of the vehicle, so levelling has to keep the beam out of oncoming drivers’ eyes at every weight.
Beam pattern. The dipped beam is asymmetric, throwing more light along the nearside verge than towards oncoming traffic. The pattern is designed for right-hand or left-hand traffic, so a vehicle that moves between the continent and the United Kingdom or Ireland needs headlamps approved for the traffic side it drives on.
Daytime running lamps. Directive 2008/89/EC made daytime running lamps compulsory for new types of M1 and N1 vehicles from 7 February 2011 and for new types of other categories from 7 August 2012. The obligation applied to new types, so earlier models approved without them remained legal. They switch on automatically when the engine starts and go off when the dipped beam is switched on.
The Lamp Regulations and the 2019 Consolidation
Each lamp is approved under a device regulation, separately from the vehicle. Until 2019 almost every function had its own: Regulation 6 for direction indicators, Regulation 7 for position and stop lamps, Regulation 87 for daytime running lamps, Regulation 112 for headlamps, and so on. On 15 November 2019 three regulations entered into force that combine them into one document per family of devices.
| Regulation | Covers | Combines former Regulations |
|---|---|---|
| UN R148 | Light-signalling devices: position, stop, direction indicator, reversing, rear fog, daytime running and side-marker lamps, among others | 4, 6, 7, 23, 38, 50, 77, 87, 91 |
| UN R149 | Road illumination devices: headlamps, front fog lamps, cornering lamps and adaptive front-lighting systems | 19, 98, 112, 113, 119, 123 |
| UN R150 | Retro-reflective devices and markings | 3, 27, 69, 70, 104 |
The consolidation was an editorial exercise: the technical requirements were carried over, not rewritten. Delegated Regulation (EU) 2022/1398 added all three to the list of UN Regulations in the General Safety Regulation. Approvals already granted under the former regulations were not invalidated, which is why datasheets and tenders still quote both the old and the new numbers for the same function. Our article on ECE R148 covers the consolidation, the new approval mark and the transitional provisions in detail, and ECE Regulations 6, 7 and 91 explains the former requirements for indicators, position and stop lamps and side markers.
E-Mark and e-Mark: Reading the Approval Mark
Two marks look alike and are often confused, including by suppliers who quote “e mark certification” without saying which one they mean. They come from different legal systems.
The number identifies the approval authority, not the factory. A lamp built in one country can carry the number of another because that country’s authority tested and approved it. The rest of the mark, the approval number and the function symbols, tells an inspector which regulation and which functions the lamp is approved for. That is the point of the system: a roadside inspector, an approval authority or a buyer can confirm compliance by reading the lens, without testing the lamp again.
Because the EU now applies UN Regulations for lighting, a road lamp normally carries the E in a circle. When a supplier offers an approved lamp, ask which mark, which regulation and which series of amendments, and check that the functions in the mark match the functions the vehicle needs.
Testing and Conformity of Production
An approval is granted on test results for samples of the lamp, measured by a technical service that the approval authority has designated. The tests check the light distribution against the minimum and maximum intensities in the regulation, the colour, and the markings. Approval then binds the manufacturer to conformity of production: every lamp built afterwards must match the approved type, and the authority can check that it does.
LED lamps with driver electronics also fall under electromagnetic compatibility requirements, which the General Safety Regulation applies through UN Regulation No 10. On a military vehicle the same lamp may also have to meet MIL-STD-461, because radios and sensors on the platform are far more sensitive to interference than a car radio.
The same rules apply to aftermarket parts. A replacement lamp, an auxiliary lamp or an LED conversion must hold approval for the function it performs to be legal on an EU road vehicle. Each lamp in our LED rear lights and LED signal lights ranges lists on its product page the ECE regulations it meets, so a lamp can be matched to the approval route the vehicle specification names.
Military and Specialist Vehicles
Article 2(2)(d) of Regulation (EU) 2018/858 states that it does not apply to “vehicles designed and constructed or adapted for use by the armed services only”. Article 2(2)(c) also excludes track-laying vehicles, which takes tracked armoured vehicles out of scope whoever operates them. This is a change from Directive 2007/46/EC, under which approval of armed services vehicles was optional; under the 2018 Regulation they are outside its scope.
Vehicles for civil protection, fire services and forces responsible for maintaining public order are treated differently. Under Article 2(3)(b) the manufacturer may apply for approval, provided the vehicle meets the requirements. The word “only” in the armed services exclusion also matters: on the face of the text, a standard commercial vehicle that the armed services happen to use is not excluded, so logistics trucks and support vehicles on commercial chassis normally arrive with EU type approval.
Outside type approval, the lighting of a military vehicle is set by the contract and by national defence and road rules. Platforms that move on public roads in peacetime still need lighting that other road users recognise, so a road mode built on R48 installation and approved lamps is a common requirement. Blackout, convoy and infrared lighting are not functions in the UN lamp regulations, so they carry no UN approval and follow military standards instead. Our military blackout lights are built for that tactical side of the requirement, alongside road-approved lamps for the other.
Before ordering, establish three things: whether the vehicle falls inside or outside Regulation (EU) 2018/858, which lighting documents the contract calls up for road and tactical modes, and which approval marks the authority accepting the vehicle expects to see.
Frequently Asked Questions
No. CE marking is generally the manufacturer’s own declaration that a product meets EU product legislation. The E-mark records a type approval granted by a government approval authority after testing by a designated technical service. A lamp for road use on an EU vehicle needs its approval mark; a CE mark alone does not make it road legal.
Not as approved road lamps. The United States is not a party to the 1958 Agreement, so a lamp certified only to FMVSS 108 or SAE requirements holds no approval the EU recognises. Many commercial and military lamps are built to meet both systems and carry both markings, which is the practical answer for fleets that operate on both sides of the Atlantic.
UN Regulation No 65 covers special warning lamps, which emit amber, blue or red light depending on their use. Approval to R65 covers the lamp itself. Whether a particular vehicle may carry and use it, particularly in blue, is decided by the road traffic rules of the country where it operates, so check those before specifying beacons for recovery, engineering or military police vehicles.
Yes. The United Kingdom has been a party to the 1958 Agreement since 1963 with distinguishing number 11, and that membership does not depend on EU membership. UN approvals it grants carry E11. EU type approval is a separate system: the lower-case e-mark is issued by the approval authorities of EU Member States under EU law.
