E-codes for UK based vehicles are different than for the rest of = Europe (the cut-off is angles the opposite direction). Most Europeans = really don't know how bad our sealed-beam or DOT lights are. E-code = lights for 85 and earlier are standard 7" round w/H-4 bulbs of your = choice. Cibie, Hella, Bosch or whatever all seem to work fine to me. But = on 86 and later Vanagon with square lights, factory E-code lights are a VAST = improvement over the DOT lights that unfortunately came to the US and Canada. = At the time that our beloved Vanagons were built, DOT required an incredibly = ridiculous beam pattern far short of what was required in Europe...you'd think that = DOT's intention was to light 10' in front of the bumper and no more!!!! = In the earlier and mid-eighties, police would pick out these illegal e-code = lights on the Mercedes and Porsche cars (it was pretty obvious because most had = small round or 5x7 sealed beam lights). I don't believe that this is the = case anymore because modern lamps look like e-codes but = aren't. I suspect that the DOT specs have changed since then because the new = Porsche and Audi cars have a much better pattern than ever before in the US. = I've heard that European lamp manufactures have developed a new duel standard = lamp for US and LHD European cars.
