When I got this Samuari, I noticed that there is red light installed just below the radio. It only comes on when headlight is activated. I know truckers use some sort of light at night while driving. The only thing I think of is to remind driver to turn headlights off when not driving or at sunrise. Tempting to take it off but come think of it, I don't think it has an alarm to notify you that the headlights is on when departing the Samuari.
