I read somewhere that the 881 bulb is what's used in the RSX and an LED is available...... 881 LED Bulb | eBay
I might try these out. I currently have some LED driving lights mounted on the brush guard, and they by far out-perform the OEM lighting. I was thinking of a single row LED light bar mounted just below the roof line, but they are big bucks. Maybe these 881 LED's are all we need?
