Most trucks do not come equipped with cab roof running lights. These lights are mandatory factory equipment on big rigs, one ton and above. The two outside lights are known as clearance lights, the three inner ones are marker lights. Combined they give oncoming traffic a visual fix on your truck, offering you additional safety.
Kits come complete with lights, wire harness, quick splice connectors and a dash mount panel with toggle switch plus indicator light. The switch allows the Cab Roof Lights to be operated independently of the headlights. All kits meet SAE specifications.
