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
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.
