    I recently installed new taillights, third tailight, grille w/ raptor lights and new headlights (all new LED bulbs and casings). I seem to have everything wired up correctly but the final piece is the LED side markers keep tripping my 10amp fuse. Nothing else/ extra is wired to them.

    Is this a light issue or a fuse issue?

    They are cheap LEDs off of Amazon. Described as not polarity sensitive, Voltage: 12V~24V, power. 2W/bulb.

    Assuming it only blows when the lights are connected they are either connected improperly or are just shit lights.

    Pull the LED bulbs out and replace them with your original bulbs. See if your fuse problem goes away. If it does, the cheap Chinese LEDs are your (very common) problem.

    So, the fuse trips even with no bulb in the socket. Any thoughts?
    Put a new fuse in, start the truck and 'pop'.

    I should add, when I first wired the raptor lights I tapped them into the side markers. I then decided to add a fuse tap adapter and have them on with the headlights. Could I have fried the side marker housing/connector when I had the raptor lights tied in?

    You sure you didn't pinch any wiring when installing the lights?

    To be clear which fuse is blowing?

    Under the coinbox/ instrument panel 'fuse 3', 10amp
    "(TAIL) Tail lights, license plate lights, parking lights, multiport fuel injection system/sequential multiport fuel injection system, instrument panel light control, illuminations)"

    I've gone back over where I had tied in the raptor lights and everything is clean. Can't find a pinch.

    Did you pull all of the side marker bulbs - and any other bulbs on that same circuit - out?

    As for tapping into the side markers for Raptor lights, any time you "tap into" a harness, bad things can happen. I'd check the point where you tapped in to see if it's shorting out on something. Without any bulbs in any socket on that circuit, the only way you'll blow a fuse is a dead short in the harness.

    As a side note, I've rarely ever seen a single product as destructive of a vehicle's wiring as "Raptor lights." Between abysmal quality Chinese products and hacked installations, fixing the evils caused by those bad boys makes our Service department some good money.

    Embarrassingly, didn't even occur to me to check all the other lights I need off this fuse. They're all out. Looks like some service department will make money off me too. Appreciate the insights. If anyone has any thoughts Id totally appreciate it. I'm lost.

    At one point everything was working great. Don't know what happened.

    What was the last item connected that blew the fuse? That would be where I would go.

    When the fuse blows, all electrical components on that circuit quit working. That's why all of the lights are out. If you remove all of the LED lights you installed, then power the circuit up, the fuse should not blow unless you have a harness problem. If it does not blow, start re-installing your original blubs one by one, checking to see if the fuse blows. When (or if) it does, you found the problem. If it doesn't and you have all of the original bulbs back in, it was one of the LED bulbs causing the problem.
