Have a ford tractor and the headlights and working lights on cab are dim compared withour 2nd tractor of the same model. Are off white instead of bright white. Could this be poor earth ! It is on all lights not just some or 1. Any help welcome

Battery condition , different bulbs , dirty lens or glass !.

Poor earch can do it, otherwise the wattage of some of the bulbs can be different also standard bulbs vs hallogen.If you can swap 1 bulb try it, if it makes no difference then its poor earth.

If all lights on then you turn on the hazards on they struggle and all light dim then yet starting is fine even when a cold start, I'm thinking the whole lighting system has poor earth somewhere or maybe poor power supply - yet to check volts at lights. Thanks
