    Hi fellow members. Hope someone out there can confirm what this is. I think it’s an inline fuse but haven’t seen one like this before. My truck had aftermarket headlights in it when I got it and one has gone off and on a few times in last month or so so I disconnected it and bulb looked ok and I put some dielectric grease in socket. Went out again and I saw insulation looked burnt and smell of burnt wires. Cut insulation and discovered broken, burnt what I assume is fuse. Has GW 10 A on it. Picture shows what I’m talking about. Anyone know where I can get one like this or can I install another type?

    Mod list... Well, my paint is factory.
    Hard to tell in the blurry pic but it looks more like a diode.

    Can you provide a better picture so we can identify it by the markings?

    I’ll try to get a better picture. I thought it looked more like a diode also but I didn’t see a direction arrow or anything like that on it. It’s hard to get good picture because it’s broken but I’ll try

    Here are the best ones I can get. Like I said I think it has G W 1 0 A. These are only letters and numbers I can see. Not sure if anything else where it is broken or notIMG_3792.jpgIMG_3791.jpgIMG_3789.jpg

    Possibly a Goodwork Semiconductor 10A diode. Not sure if it’s a TVS or a rectifier. Might need one of those angry pixie wizards to pipe in here.

    I’m sure there’s an electronic guru on here that would know. Maybe they’ll see the post. Thanks for trying to help El Taco I appreciate it. I got to figure out something I have only one headlight at this point

    Just a 10 amp rectifier diode. You can get them from Amazon

    yep
    i would be more concerned about what caused it to fail. diodes rarely fail that spectacularly without outside forces.

    I will check the wiring going to and from where it was. Like I said the truck had these aftermarket headlights and the harness for them plug into the factory harness. I may just try to go back to factory if I can find a good set

    They are using a high amp diode to keep the low beam active when the high beam is triggered. This is done when you have projectors with a shield that lifts when the high beam comes on instead of triggering a 2nd filament or high beam bulb.

    I did this on my wifes car when we switched her headlights to oem projectors. I created a wiring harness with a diode between the low and high beam wires.

    Appreciate that. I wasn’t aware of that as these lights were on truck when I got it. Got the diode today so will solder it in tomorrow finally and hopefully I’ll have two working headlights again
