So far I havn't fried anybody but I could light them up if I wanted to. It makes it nice at night I had a guy trying to park in a dark spot one night he came thanked me when he got parked and wanted to look at my setup.

There are two different ways to do this mod.
One just uses larger AWG wire from the battery positive post and the other uses larger AWG wire attached directly to the alternator output terminal.
I ran mine from the passenger side battery positive terminal with 10 AWG wire and am very happy with Silvania Silverstar Ultra bulbs.
I did have to switch to composite headlamps with the jewel pattern reflector which also give much better light control to use the Silverstars in my 86, but I am extremely happy with the mod.
The sharp beam cutoff the jeweled lights give keep the light out of oncoming traffic faces and rear view mirrors of people I am following.
The extra brightness probably doubled how far I can see when the high beams are on.
And getting the amp load off the headlight switch and the main power feed into the cab helped everything else out as well.
