No pics, sorry. They are mounted at the ends of the frame rails hanging under the front bumper. They stay put until I hit something, then they rotate back. I had the bulb come out once, but it didn't break.
Yes it is a simple swap of the bulbs. I bought mine at a small town NAPA. For about 50 bucks I got a pretty good light settup. I just popped one out and got the info off the back. It is a
Wagner 13v
4509
100W
(looks like a 15 under all that-- Beam spread?)
They are clear (no lens pattern) and have pretty heavy fillament inside.
They do draw some juice. I fried my first attempt at wiring them up. Worked for about 20 min. and litterally cooked the wires. (I think it was 14 guage) Now I have 10 (maybe 12) guage wire to them. I don't leave them on when the truck is not moving for more than a few minutes. They do get hot, but I haven't had any problems with them.
My switch to turn them on is pretty slick. I used a relay and wired it to my dome light switch. (I got the little pop-o-matic lights in the OH console so who needs dome light switch?) When I rotate the headlight switch, it closes the relay and turns 'em on.
I keep thinking about moving them up into the bumper, but it seems to be a pretty low priority.
