Hello all, guys quick question, do LED bulbs work OK on the C4? Also do they need to be CANBus ones? Thanks.

I've got LED bulbs (501 type) in my front and rear sidelights. They work fine, but since they're not CAN bus compatible the front ones do generate errors in the warning log. I tried using LED bulbs in the interior lights and they were too bright, I went back to standard ones.

If you were going to use LED bulbs for indicators they would need to be CAN bus compatible else they would flash too quickly, but I haven't got any personal experience with this.

I wouldn't try using LED bulbs for headlights, main beam, or fog lights.
