This may be a dumb question...however, I know some of you guys/gals have replaced the not so bright round lights up front with some bright aftermarket lights! My question is are any of you use-n the existing wire-n from the old ones for the new ones or do you have to run a new wire to the fuse box because it would over load that curcuit to use the factory wire-n? Want to change mine out because the way they are, they really don't have much of a use...M/O
