ok im not sure if this even a problem but im sure it isnt supposed to be like this..

so i installed my new jdm tail lights when the lights are on the brake lights and the reverse stay on... shouldnt the reverse lights turn off and on with when putting in and out of the reverse gear???

here is a picture of how they look when the lights are on in neutral! is this right????

 

hmm did u cut wires if so i think u might of mixed it up. try double check

 

maybe the bulb in the reverse light is a parking light, you lose one parking light when installing JDM taillights.. make sure you leave it out

 

yeah make sure you're actually putting the reverse light bulb in. the parking light isnt used.
