i would love to switch over as many light to LED as i can, how do i know what part will work in my car?

 

you go by bulb number, each LED has an equivalent number that they use.

Low Beam Headlight Bulb Size: 9006
High Beam Headlamp Light Bulb Size: 9005
Parking Light Bulb Size: 3457ALL
Front Turn Signal Light Bulb Size: 3457ALL
Rear Turn Signal Light Bulb Size: 3057
Tail Light Bulb Size: 3057
Stop Light Bulb Size: 3057
High Mount Stop Light Bulb Size: Assembly
Fog/Driving Light Bulb Size: 880
License Plate Light Bulb Size: 194
Back Up Light Bulb Size: 921
Front Side Marker Light Bulb Size: 194
Rear Sidemarker Light Bulb Size: 194
Ash Tray Light Bulb Size: 194
Glove Box Light Bulb Size: 194
Map Light Bulb Size: 194
Dome Light Bulb Size: 578
Step/Courtesy Light Bulb Size: 194
Trunk/Cargo Area Light Bulb Size: 912

 

wooo, good info here!

are some of these spots better left alone?

 

Use your judgement. Obviously don't change headlights and stuff.

Mostly you'll just buy a bunch of 194s and the dome light 578.

 

Well I turned the light around and it will not work that way? I do not get why all the LEDs will not light up. Like I said when plugged into the map lights all the LEDs light up but in the under the dash step lights only the center one lights up. I would like to know if anyone else who has put LEDs in the step lights has had this issue?

 

...Thanks everyone for helping a member, and taking the time to research & post : ) I appreciate 4-Sure Thank You!!!

 

I have LEDs in my step-lights and I'm not running any issues with it.

 

Ditto.

 

What kind of LEDs are you running? I have been RACKING my brain trying to figure this out. Checked the fuses the wiring and nothing yet. I just can only get that center LED out of the seven to light up so its basically I paid for a 7 LED bulb that is only lighting up with 1 LED.

 

I bought a 7-LED 194 Red bulb from V-Leds.com
