What You Can Still Replace Yourself
The Peugeot 308 has LED headlights, so there is no dipped-beam bulb to change. Several other exterior lamps are still conventional bulbs, and those you can replace yourself:
- Reverse Light — W16W.
What to Do If a Light Fails
There is no user-serviceable bulb in the Peugeot 308 headlamp. If the dipped or main beam fails, the headlamp module is the part that gets replaced — a dealer or auto-electrical job.
The lamps you can change yourself are reverse light (W16W). Those are ordinary bulbs and take ordinary tools.
MOT note: a failed headlight is an automatic MOT failure whether it is a bulb or an LED module, so it is worth diagnosing early rather than at the test.
LED Headlights and the MOT
The Peugeot 308 came with LED headlights from the factory, so the usual “is an LED retrofit legal?” question does not apply — there is no halogen housing to retrofit into. The factory unit is type-approved as fitted.
What the MOT does check is that the lamps work, that beam pattern and aim are correct, and that lenses are not badly clouded. A partly failed LED array can still fail on beam pattern.
Frequently Asked Questions
What headlight bulb does a Peugeot 308 use?
None. The Peugeot 308 has LED headlights as standard across the UK range, so there is no replaceable headlight bulb. Only two front-lamp versions exist anywhere: LED technology headlamps and Peugeot Matrix LED Technology 2.0. There is no halogen variant even in mainland Europe. Rear fog is P21W.
Which bulbs can I still change on a Peugeot 308?
Several exterior lamps are still conventional bulbs: reverse light takes a W16W. The headlight itself is a sealed LED unit.
Are LED headlight bulbs legal in the Peugeot 308?
The question does not really apply here. These LED headlamps are factory-fitted and type-approved as they are. The retrofit-LED rule that catches people out applies to cars sold with halogen headlamps, which this is not.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
