The turn signal definitely let the smoke out.
The DRL uses the same, but white. Because SSV, I swapped the white drl's into the turn signal spot for now.
See if I can find any leds i like i suppose.


Strange that the DRL has a dual filament bulb. :oops:

Aren’t those your new AlphaRex headlights? Seems fishy that a bulb would already burn out.
They are, and it does. Maybe it was a cheap bulb, maybe there was extra load or something from poor connections, no clue. Slightly annoying though.
Damn GM engineers expected light bulbs to last longer than the vehicles apparently. Since you have to pull a damn bumper to change a headlight bulb. Lol

I'm assuming that it was just easier for them to manufacture that way. Use the same dual filament for the turn signal and the drl.
Drls online are useless anyway, their programmed out of the bcm, there's no way to ever turn them on.

@Fless called it! Double male barbed coupler and a release tool. For the tool, I've never had one of these let me down: https://www.amazon.com/ARES-70024-3-16-Inch-Scissor-Disconnect/dp/B0195XBPPQ

Although, you won't be needing it to install your repair parts.

If it weren't for ethanol, I'd pick the double barbed fitting over the compression union, unless that double barb is stainless. If it is zinc-coated steel as it appears to be, you did good ordering those plastic compression unions. If they ever leak, get stainless double barbs.

I just got those push fit union connectors, they are the shit. And the quick release works well. Very cool! I think the barbed fittings maybe aluminum, they are very light and non-magnetic.

The term “salt truck mechanic” makes me cringe and reach for a BFH to fix any problem you run into. Michigan winters play hell on vehicles, I do my best to limit my driving during those months (all ten of them), or at least give them baths often.
When I moved from Colorado to Virginia back in 2020, it was a huge deal to me for the main reason that I would now have to deal with corrosion on my cars. I HATE that. I grew up in Pittsburgh, and was so happy to live in dry country Colorado after college. Of course, as I write I'm sitting in Columbus, OH with our previously pristine, Arizona-owned for most of its life, '07 XL Denali sitting outside drenched in salt spray. I can almost hear the rust eating away at that clean metal.
