If your question is about how to access the tail light "bulbs", there are NO TAIL LIGHT BULBS in your tail lights. The tail lights are LEDS. IF you need to access the LEDS, you carefully 'squeeze' the lens and pop them out of their beveled rings (the chrome rim). However, your tail light assembly may have the lense "rubber-seal'ed" to the camper shell. Use a plastic putty knife to SLOWLY remove the lens assembly as you separate the lens assembly from the guey. In either style, you will find the lens assembly is attached with two screws to the camper shell. My MPG came from the factory mis-wired. i.e.,tail lights were the brake lights (leds), and brake / turn signals were wired to the dimmer tail light (leds). I remove the lens assembly (mine had the guey stuff!) swapped the wiring, reinstalled, and was on our way. 20 mins per side. Heartland techs never figured it out and kept claiming "MY CAR WIRING WAS WRONG". I think the techs never would believe it came mis-wired from the factory! But, the techs were good people and wished us a safe trip on our 6 hour drive way home from the dealer! Leave me a post if you need more information... You lights wired correctly?
