I have a 1982 300sd. Stock wiring and relays. I just got my Bosch H4 euros. The good folks at Capitol West Co. in Sacramento, CA. sent me a pair of high wattage bulbs I ordered. 100/90w H4 P43T Xenon Halogene in the Heliolite brand. Wiletta who owns the place said that she uses these in her 78 Mercedes and a 1991 model with no problems and has done so for five years.

Daniel Stern lighting emailed me and said, "You must stick with stock wattage to use your existing wiring. There is a persistent (and incorrect) rumor that Mercedes are so well built that you can safely and effectively run high-wattage headlamp bulbs without damage. Do so at your own great risk.

Use ultra high efficacy H4 bulbs, $17/ea, and H3 Gold bulbs, $13/ea."

Any of you have a definitive answer for me before I damage something?
