Hi,

I bought a C250d with front end damage. I've replaced the headlights but they don't work at all - not even the indicators work on it. Any ideas what could be wrong? All the plugs are in and the rear lights work. Just the headlights don't work at all.

Many thanks

Do they have power at the connectors? Did you check fuses and relays and use a dmm to verify?

You didn't indicate which lights you bought, so these are the possible scenarios:
1. You bought the LED lights and attempt to install in a halogent-light car.
2. The LED lights you bought are missing the control modules.
Check the rear lights. When they're on, are they in shape of a curve? If yes, then your car has halogen and you should buy halogen headlights.

Didn't check the power to the connectors, will check that tonight. Checked the fuses but not the relays - where are the ones for the headlights?

I know which ones to buy, they're the intelligent LEDs with the double led projector headlamps. I've bought the control packs and used the original ones for the passenger side but there's nothing on either headlight. It can't be right - there's gotta be something wrong somewhere.

The original lights had double led projectors?

Yep, 100%.

I think you'll find that they need to be coded to the car.
