I own a 2002 SL2 sedan with keyless entry..when i unlock the car with the key fob the headlights flash as they are supposed to..My question is is it possible to mod the car so the Tail lights will flash with the headlights? I park in a parking garage at night and from a distance it is difficult to often see the headlights flash if a vehicle is parked beside my car..

 

I would assume that all it would take is to isolate the "flash command" signal and reroute it (via a blocking diode) to the Instrument Panel Junction Block (IPJB) and connect it to the BRN wire coming from the parking light switch.

Unless you are "electrically savvy", this is much easier to say than to do ....
