If you are looking for a cross-reference for a door marker light bulb, it's a GE model 194. For those of you who like to know Delorean cross-references, I found the following although it was quite obvious. A side marker light in my door burned out, but none of the manuals said exactly what the bulb is other than it is a 12 volt 5 watt bulb. Among my shop spares, I found a pack of bulbs that look the same, but the package does not specify a wattage. So being the tech that I am, I measured them. On a car battery that I had sitting around, it had 12.35 volts. A factory original bulb pulled 326mA, and my new bulb pulled 235mA. By doing the math, here's what I found. Factory original bulb drew 4.03 watts, and my replacement drew 2.90 watts. So much for the OEM being a 5 watt bulb, eh? I'm sure there are higher wattage bulbs available, but I'd rather not run my battery down as fast nor heat up the light fixture while keeping the doors open at shows. And if this burns your car up, don't blame me. :) I've said too much already.... Walt Tampa, FL
