What can I do for my dim headlights on my 94 C4? The stock lights dont seem to be bright.

http://classicgarage.com/20recheadrep.html  This is what I use in mine. They allow you to do away with the stock "sealed beam" and use H4 bulbs which are low and high beam combo bulbs. These bulbs can be found on line labeled for"off road use only" at 80/100 watts for low/high beam. My "old" eyes really like the off road bulbs  and I've had no issues with the higher wattage damaging or melting the headlamp wiring as some suggested.
