I think I know the answer to this:

What's the census on 80/100 watt bulbs in the stock DOT light housings on a
Coupe Quattro (or any type 89 or other model for that matter)?

I ordered a pair of bulbs, and they turned out to be 80/100w rather than
stock wattage...  They can be returned, but I did some research on OSRAMs
site and it says that 45/65w bulbs have an acceptable error up to 50/70
watts.  By that math, the 80w low beam is only 10 watts higher than the
stock acceptable high beam (70w).  So is 10 watts that significant?  What I
worry about use over time...  70 watts in a stock bulb for limited periods
at highway speed with lots of air moving over the lens is different than 80
watts continuous sitting in traffic, every night...

So should I fire the 80/100 watt'ers back to the seller to avoid barbecued
wires and cracked lenses or...?

Thanks in advance,
