Brighten up your driving experience with this simple upgrade inside your underhood relay box. Simply install the All Lights On module to allow your high-beams, low-beams and fog lamps to simultaneously illuminate the road ahead. Once installed the All Lights On module will keep your fog lamps on when you turn ON your high-beams. When the high-beams are NOT turned on your low-beams and fog lights will function normally. Fitment: 2007-2017 Toyota Tundra with factory installed fog lamps Installation: 1. Open the hood and remove the relay panel cover. 2. Remove the relays labeled: FOG and DIM 3. Insert the relays through the All Lights On boards with the wire connection facing towards the top of the relay. The board will make a firm connection with the relay. 4. Reinstall the two relays back into their original location and install the relay panel cover. Operation: MY2007-2013 (Separate high and low bulbs): High beams, driving lights, and fog lights all on when high beams are enabled. MY2014-2017 (Dual filament bulbs): High beams and fog lights on when high beams are enabled.
