Agree 100%, but this is why they put these TIPM's in, so there are no fuses for most lights now, and you can program the lights, change them for like DRL's your lows, or your fogs, etc. the only lights with fuses now on the 4th gens are the rears and that's because they wire harness for the trailer is connected to them and who has never blown a fuse when plugging in your trailer lol. More money for them, I am told the TIPM module or (light controller) goes for about 800$ on the Ram, + labor to replace it, not bad instead of a 50 cent fuse the owner can change himself.
here is some great info on TIPM's, the guy breaks down a Jeep unit and shows how its made.
