Hi Benz

I once used 100/120W clear rally H4 bulbs in my Euro 123 headlights. There were no problems with heat at the housing but when I started to play around with my "optical horn", ie flasher, there was a burning smell from the combination switch from over arcing. The combination switch was marginal to begin with. Other than that I experienced no problems.

I do have to add that after that incident I changed them back to the normal ones for the following reasons 1) the 100W were blinding to oncoming traffic 2) Alternator/battery drain (60W alternator) and 3) incident above.
