Are two bulbs all I need for the whole climate co trim to light up?

There are a total of 8 bulbs in the Hvac control. 3 on each rotor knob and 1 on each temperature slide. This pack comes with 20 LED's.

I soldered them in and bench tested them. They all worked on a 12v power supply. But dont work plugged into my truck. HELP

I would assume that you soldered them in backwards. You put positive to negative and negative depositive on the lights if you check the fuses and everything else on the dash works, reverse polarity
