The next time I take my tail light lens off, I'm going to measure the wattage. From the looks of it, it doesn't seem to put out anywhere near the light that a 50 watt bulb should. So far the lens doesn't seem to heat up at all. There seems to be plenty of room between the bulb and the lens, so I'm not too worried about melting problems. I'll keep you all posted. Walt Tampa, FL
