Aftermarket bulbs for guages

LED? What year truck?

 

Really recomend against blue if you night drive much, it severely messes with nightvision. But not my truck

Twistlock style or push in?

Twist style:

Push in style

And then buy more leds

As for make, led, basically if it works when you put it in, its fine, i bought 20 or 30 of the cheapest leds i could find. Maybe 3 were doa but i only spent 30$ so im still at 1.11$ each so i dont think its that bad. They were dimmable too

 

Stuff above is what i used in my 94 t600 so should work fine

 

You should need ONE of those pigtail things and 19 twistlock styles, 20 total lights if all guage slots are full

Pyro is only one thats different

Remove old twistlock gently with pliers. Throw em straight in the trash, that old plastic will disintegrate on you trying to reuse it.

Also, as stated, buy 30 when you settle on color that way you have spares

Recommend getting a few colors to test which is actually the color to use

And also, replace dimmer knob /switch while in there
