The other night i was driving around with some friends when one of them came up next to me and told me all my tail lights were out. This was odd, since i checked every bulb the night before. When we stopped, i was playin with some of the knobs. I found out that for my guage cluster dim, instead of dimming the cluster, it dims the tail lights and turns them off, but not the headlights. Three questions. Is this a factory option? Do i have to search for a possible problem? Or could it be that someone did this on purpose for illegal use?
