I've had no probs with my Canadian DRL's. Hook 'em up & go! One of the best mods I did to my '98. First mod I did to my '97 when I got it.
I've got the G.E. Nighthawks. The '+' 90% ones. Best lights I've found without going to HID's. And I've got a shelf in my shop with about 10 different pairs of lights that I've tried. Probably about $500.00 worth, just sitting there. And they can stay there since I found the Nighthawks.
The 4-hi kits that I have, are ebay specials. I've had a few probs with the relays. If you are to do this, & I highly recomend it, is get one of 'Mean Green's' kits. Apparently a better design, with an eaier install style.
This is a safety thing, in a way. I wouldn't own a GMT400 without this mod!
