On the site it asks for "Wide" & "Narrow" option. Im guessing this has to do with some dimensions. What the maximum number of LEDs you can have on an 1157 type bulb for it to properly go into a tail light housing?

I didnt know that they made instrument cluster LEDs as well. I may have to look into those as well. Can they still be run on the dimmer switch or is it a one brightness, and thats it?

Definitely going to get some spares for the toolbox but keep the incandescents in the trunk of the car.
