| Generalities relating to changing a bulb | Misting is normal, and how to clean the lenses |

Generalities relating to changing a bulb
In some weather conditions, such as low temperature or humidity, you may see misting on the inside of the headlamp and rear lamp glass. This is normal, and it will disappear after the lamps have been on for a few minutes.
The headlamps have polycarbonate lenses with a protective coating, so clean them with care:
- Avoid: dry or abrasive cloths, detergents and solvent products.
- Use: a sponge and soapy water, or a pH neutral product.
- High-pressure washers: on persistent marks, do not keep the lance pointed at the headlamps, lamps or their edges for too long. This protects their coating and seals from damage.
Light-emitting diode (LED) headlamps and lamps
Depending on the version, these headlamps and lamps on your 408 use LED technology:
- LED technology headlamps.
- Peugeot Matrix LED headlamps.
- Offset daytime running lamps/sidelamps/direction indicators.
- Direction indicator side repeaters.
- Side spotlamps.
- Full LED technology rear lamps.
- LED technology rear lamps.
- Brake lamps.
- Third brake lamp.
- Number plate lamps.
To replace any of these, contact a PEUGEOT dealer or a qualified workshop. Do not touch LED or Full LED technology headlamps, because there is a risk of electrocution. Never look too closely at the light beam of LED technology lamps, as this can cause serious eye injury.
Front lamps
The front lamp layout depends on which headlamps your 408 has.
Model with LED technology headlamps:
- 1. Main beam headlamps.
- 2. Dipped beam headlamps.
- 3. Direction indicators.
- 4. Daytime running lamps/Sidelamps.
Model with Peugeot Matrix LED headlamps:
- 1. Dipped beam/main beam headlamps with Matrix Beam function.
- 2. Dipped beam/main beam headlamps.
- 3. Daytime running lamps/Sidelamps/Direction indicators.
All of these are LED lamps, so a PEUGEOT dealer or a qualified workshop must replace them.
Rear lamps
There are two rear lamp versions: models with LED lamps and models with Full LED 3D lamps. The numbered lamps are:
Scroll the table sideways.
| No. | Lamp | Type |
|---|---|---|
| 1 | Direction indicators | LED |
| 2 | Brake lamps/sidelamps | LED |
| 3 | Sidelamps | LED |
| 4 | Foglamps | P21W |
| 5 | Reversing lamps | W16W |
You change the reversing lamp and foglamp bulbs from outside the rear bumper:
- Remove the screw(s): undo the fixing screw(s) on the access flap under the bumper, using a Torx screwdriver or 10 mm hexagonal socket.
- Unclip the flap: unclip the access flap.
- Remove the bulb holder: turn the bulb holder a quarter turn and take it out.
- Foglamp: turn the bulb a quarter turn and replace it.
- Reversing lamp: pull out the bulb and replace it.
If you change a bulb within a few minutes of switching off the ignition, take care not to touch the exhaust, as you could burn yourself.
Frequently Asked Questions
