We used 2- 288 watt rgb lights from tss mounted on vertical stands on the sides of the exit
doors. We have green fir soaps, blue fir sealants, flashing rgb for triple foam and red for dryers. After we added these lights we installed a hot wax retrokit to our 3 g-5 machines, that came with 2 yellow led tube lights from g&g mounted on the overhead bridge itself ( no pictures currently but i can get them) and in addition to those we added another 144 watt yellow light from tss on the exit end of the overhead rack facing down on the windshield along with tss' large flashing simoniz hot wax sign on the wall next to the drivers window. The yellows and flashing sign go on only during hot wax function but these lights completely illuminate our bays day or night! Obviously night time is best and when they are on act as quite the eyecatcher from the street. With help from tss and mean well, the ac/dc inverter company, i built a control box that takes the signals from the digital output cards and turns the lights on accordingly...... overall cost per bay without labor for just the 2 vertical tower mounted lights and controllers was about $ 3,000. Well worth it for us. The yellows and sign were part of a package we added to the g-5units to give us hot wax capabilities, i imagine the lights seperatlry would add maybe another thousand bucks or so. Did we go overboard? Yup! But very happy with the results!
