This is what comes with the bulbs from the distributer. I don't think there's a danger of cracking the lens, and if you're reading this you needn't worry about the voltage at the back of the bulb.
but it wouldn't surprise me to find that high-wattage bulbs don't last as long as the stock bulbs.
The industry accepted life of a standard wattage bulb is some 200-300 hours. Of course, some are going to fail earlier and some are going to last your lifetime. Time to Fail is a standard bell curve around 200-300 hours. Typically, the life of a high wattage bulb is less than half that of a standard bulb. Some are rated as low as 50 hours. It is heat and vibration that kills any bulb, and with a high wattage, there is much more heat resulting in a much softer filament which is much more suseptable to vibration. When running high wattaage bulbs in smaller lamps designed for 55 watt bulbs, not only do you run the risk of cracking your lens, you significantly reduce the normal life of the bulb. In addition, the condition of your charging system can influence bulb life. What is the voltage at the back of the bulb? Is the regulator allowing spikes on the power? Beyond that your habbits can influence bulb life as well. Do you turn your lights on before starting the engine? Do you turn the lights off after shutting the engine off? Both actions will cause spikes that can take out the bulbs prematurely. Even normal operation of high load accessories like the air conditioner compressor or the heater fan, create surges on the power when cycling on/off that reduce the life of a hot bulb. This is especially the case with high wattage bulbs.
