Using liquid electrical tape to fix flaky insulation on headlight wiring

I’ve cut open the headlight lens to replace them with a new pair. Inside the headlight body, I can see the wiring has lost most of its insulation. What’s still there is flaking off as I touch it.

Can I use liquid electrical tape/insulation to “make” a sleeve on these wires? If not, is there another solution?

I have already replaced the fiber optic lines for the angel eyes with new ones, so that’s not a problem. I’m talking about all the other wires in there that’s flaking its insulation.

Sure that will work, just know that the hardened liquid tape will be subject to the same heat levels as the old insulation.

I'd recommend flaking all the old insulation off first. The liquid tape isn't going to really help much if the substrate it's bonded too is weak and flaking. It will just come off with the flaking insulation.

I'd consider shrink wrap if they can be easily backed out of the connectors and gotten to. Don't cut them for it though.

You might have to consider replacing them altogether. Not fun, but do-able.
