Hey guys, I have a little problem. The lights that light up the 2 wheel drive and the 4hi and 4lo buttons went out. For a while it seemed to only be the 2 wheel drive that was out, now all three are out. I tried messing with the dimmer switch and it doesn't fix it. Is this bulbs that need replaced or would it be a fuse. I can't seem to find anywhere what bulbs these would be to replace.. Any help would be appreciated!!
