Bulb Keeps Burning out on Simplicity 1630L

Just bought a used Simplicity 1630L. Love it so far. When I bought it the light was cracked off the unit so I went and bought a new light and I have gone through three bulbs already. Literally stays on for a few minutes and is burnt out. What gives ? Obviously its burning out from the vibration of the snowblower.

I checked the voltage going to the bulb and it stays anywhere between 12-14.

I'm close to taking it off and forgetting about a light

Thanks
Matt

It could be the vibration but I highly doubt it. Could you find an analogue Volt meter? Set on 25 DC volt range and take a reading. Most motors will push out as high as 20 volts. But it's not a steady DC current. The meter will measure the peaks. Due to that pulse current, the heat on the filament isn't as HOT as your car's current. But if the motor is putting out 24 volts DC that would blow the bulb. Check the RPM you are running that motor at. Over the Manufactures recommend RPM would increase the voltage output.
Come back with some of the answers and I can give you a further idea what to try.

I am thinking you may have a short circuit to ground that is burning up your bulb. I would check your installation of your new light and make sure no wires are rubbing on the chassis. Also, you might want to consider installing a fuse in the circuit as a safety measure. MH

I would be interested in knowing how you figured out what replacement light to use. Voltage rating?

do the simplicity blowers have DC on their headlight circuit? If so then an led light rated for whatever voltage is available would be an awesome option. Most snowblowers have AC on the headlight circuit.

.
The light was already on the snowblower. However the actual housing was cracked off the unit when I bought it. All I did was get a new plastic housing.

All the wiring is stock.
