Cool so it's a bulb socket? Noticed the mowers never had headlights that worked or harness just empty headlamps in the hood. It was down under the belt up around rear axle unplugged at the connector. Seen it goes right up to the key switch. Do some Murray mowers not have functional headlamps? Ever since I've used it seen it didn't have the headlamp harness or sockets under the hood. It was my grandfather's Murray bought from Walmart in 2004.
