Hi all. we have a W212 E350 with bi-Xenons - the '621' lamp option with ILS. Done 135k miles.
Full spec here: Car report for WDD2122232A467270 VIN number
AUTOMATIC HIGH BEAM SWITCH (IHC)
CORNERING ILLUMINATION
HEADLAMP WITH ILS, LEFT-HAND TRAFFIC
Everything's working fine - they move around at startup, automatic dip & cornering works etc - but they seem really dim compared to other car lights. My wife agrees - the crap 07 LDV minibus she drives for school work has much brighter lights.
So my questions are:
Will changing the bulbs make a big difference? how much do they fade over say 135k miles / 10 years of driving? We have them on in the daytime too, since buying the car used at 80k miles. I've read that HID bulbs are only good for 2000hrs - which at a 40MPH average, the past owner and us would have gone way over
And secondly, should I attempt this myself? I've read horror stories of lost skin/blood, hours removing wheels and wheel arch trim, etc. I'm pretty competent at 'leccy stuff and mechanical in general, but is this best left to a proper MB shop? We have a great independent nearby, and I'd be happy to bung them £60 to save myself hours of swearing. Looking at the back caps on the main bulbs, there's no way on earth my paws will fit in there.
Thirdly - the 'inner' pair of lights next to the grill look like they are LED's - I can see hundreds of wee white dots inside the lense. Are they in fact LED's so there's no bulb to change in there? So the car actually only has two Xenon headlight bulbs? Opening it up, sure looks like an LED, with no HID bulb in sight.
Powerbulbs say the car needs two pairs of D1S bulbs, so £336!
Thanks everyone for any thoughts/advice.
Cheers
Mike
