[DSK]

I've done HIDs for several year and just tried a set of LEDs on a Mercedes.

I'd say, HIDs are better. You will need the H7R bulb type for your reflector headlights. I'd also recommend a 35W 5000K colour temperature with canbus system.

LEDs can suffer issues with flicker, some issues may not be apparent upon post installation tests and as such, need additional decoders etc, which means cutting a hole in the dust cover. Also they are generally 6500K colour temp and the blue hue is too much on the blue side, unless you look at something like GT Ultra, Osram or Philips items which are very expensive.
