    As above: This is not for a Merc, its for a BMW. I want to fit LEDS to the reading lamps on my X5 Dome Light it has one reading light either side of the main dome lamp. I know that the Canbus W5W Capless Wedge Error Free LED's work okay as I have tried them..

    I have a fitting issue. The LED's that I find on ebay, are to fat in diameter to fit through the bulb housing hole (the hole the LED twists into) I cannot push the LED home far enough to engage the screw. Does anybody know a supplier (link please) who supplies a smaller diameter LED that will allow me to push the bulb home before twisting it home. Trying to trim he plastic down on the LED itself can result in uneven finger lengths or irrational demands on Mrs M to help me out (as in do it for me). Its just fiddly, dangerous and not fun.

    Has anybody got any clues who may do a W5W LED that is the same diameter fitting, as a W5W Glass bulb?

    These guys have supplied me with 2 x kits for cars which are excellent quality, and individually labelled for specific applications - I'm sure they'll be able to help you...

    The Halfords w5w led units are quite small diameter. Expensive though.

    Another issue that you may have is that they will flicker if its an auto dimming light.

    Just wanted to say that the LEDs I got from my previous post work perfectly on dimming, and dimmer without any flicker at all... (not cheap, but quality rarely is)

    Wondered why they do that! Seems really random though and only some units and not others. Will end up putting filaments back in just like the sidelights. Light colour is the least of my MB woes!

    I tried some LED's in th rear load area and front footwells of my S204, they dim up and down on and off and the LED's flickered so I went back to filaments - but in the footwell lights with a bit of lateral thinking I was able to change the W5W's for W16W's originally in the reversing lights, loads better!
