For future reference, check the GE catalogs for the size/type of bulbs that you may have.

You will have to check each catalog section for your selection on the above link.
Be sure to note the dimensions of 'your bulb'. This will help to match what you want in an LED replacement. As in the Festoon bulb front Nav light, the original is 31mm x 11mm. The LED replacement is 30mm x 10mm and you want the one with 4LEDS in WHITE. I don't know if the one with 9LEDs will even fit but it sure looks strange.
Then go to
www.superbrightleds.com to make your selections.
Hope this helps y'all out.
