aren't those reflectors? they sell aftermarket lights that have led or bulbs in them but im pretty positive from the factory they're just reflectors.
If your issue is moisture you may want to take a look at this thread - 2018 Accord Major Safety Issue. The issue in that thread is due to a cracked lens however it gives warning as how moisture in lights/light assembly's can cause havoc. Good luck on getting this figured out... keep us posted.The car has an aftermarket spoiler it could be that moister got in and messed them up
Did you end up fixing it?i know this is a old post but was this issue ever solved? having the same prob. with mine. i was hoping it was a bulb but after taking it apart realized it wasn't. any help before i spend couple hundred on new ones or having iot drop it off at the dealer for a day so they can "diagnose" it...
thank you .
no not yet, pretty much have to buy both inner tail lights or buy a aftermarket set. but i dont see to many i like. some look like spaceship lights. i want more simple and stockish looking. im leaning towards theseDid you end up fixing it?
