i never checked the voltage at the headlights with the engine running.i know the 90 96 chev trucks only had around ten volts. when you put the relay kits in to get 14 volts it helped out lots. maybe a relay kit and some night hawk bulbs would work? a good set of driving lights as back up couldnt hurt
This article presumes that "100%" output is when you take power for the headlights right from the battery, which they figure to be about 13.2V on average.
"When operating voltage drops to 95 percent (12.54v), headlamp bulbs produce only 83 percent of their rated light output. When voltage drops to 90 percent (11.88v), bulb output is only 67 percent of what it should be. And when voltage drops to 85 percent (11.22v), bulb output is a paltry 53 percent of normal! It is much more common than you might think for factory headlamp wiring/switch setups to produce this kind of voltage drop, especially once they're no longer brand new and the connections have accumulated some corrosion and dirt".

That's about a 25% drop in brightness for every volt below maximum battery voltage. That's quite a bit.
