Will I lose my highs if I get xenon lights for my '87 300E?There is the single halogen light which has lo/hi and the foglight on each side.Ideally, I want to have a xenon for the lo, a halogen for the hi , and keep my foglamps. I know that the 500E had the fogs on the front bumper, and single halogen lo/hi and daytime running light on each side.Perhaps a 500E arrangement for my 300E?Basically what I am asking is if I can retain full functionality of the old arrangement (lows, highs, and fogs) with xenon low's.Thanks.
