I keep getting bulb failure for my rear right outer lamp, it's the 2009-on "LED" type. On a hot day with the sun on it it works fine and the warning goes out, but 99% of the time it gives the error on start up and doesn't work. The wiring is fine upto the lamp I've checked that, but due to the design of the lamps it's not obvious where a bad connection may be or is there another thing to check? Not even sure what kind of light the strip lights are? are they a true LED or a bulb that lights up a tube?
