whats the best place to go to get blue dome lights and/or custom gauges that light up blue?
also is it a good idea to just spray paint the bulbs i have now for the dome lights to make them blue? any help would be great

 

Whats the year of the truck? Have you looked online?

 

Not a good idea to spray paint. The dome light bulb gets very hot and it will slowly burn off the paint

 

found this on jalopnik. might be what your looking for, might not.

Get some LED bulbs in whatever color you want and pop them in.

For the gauges, you have more than one option, depending on your year. Some Explorers had blue interior lighting. If you can find on, get the cluster and HVAC from it. Put white LED bulbs in it (the factory incandescent bulbs make the blue look more teal)

There is also a how-to on here that shows how to change the color your gauges light up.
