well christmas time is comming and i have been beatting myself up over what to get my dad . He owns and loves his 97 dodge diesel and spends alot of time driving it. My father is a man that has everything he use to be a handy man and still does alot of that work on the side(so he has every tool know to the world). but right now i have broken things down to two items i know my dad would love a Turbo cool down switch so he doesn't have to sit in his truck after a long haul or bumper lights. sinc ei am a college student i am leannign towards the lights. ever ime i am out with my father he sees them on other dogde trucks and does a dubble take to see if he can figure out how big they are to put some on. so far we have bought 2 pars of lights that have been just a lil bit off one way or another. so i am here to ask the crowd for help on finding the correct size lights that fit in the stock holes of a 97 dodge ram turbo diesel exstended cab if that makes a difference. thx for all your help

 

You Can Probably find the size of the stock fog lamps at Autozone or some were like that. I can't Tell But If I Had To Guess i Would Say 3" or so. Hope That helps

 

hmm yeah i am looking for the exact size when ever i go to autozone and make a geuss it never turns out. plus i would liek to put the few bucks in to get him a nice pair of hellas. i just love the way they burn

 

the factory lite on my truck is 3.5" diam.

Big Blue posts the part number for the Mopar lights, would probally be the best way to go if you want a factory look.
