The light on my 710 isnt exactly bright iether. Now I know that you can make it whatever color you want by adjusting it in the menue. For your..I went out to my car and tried playing around. It is its brightest on the one of the 3 main colors. red, green, or blue. THis is because there are 3 little LED lights that change intensity for whatever color you try and make. The only way to make it brighter is to make a color by making the 3 individual colors brighter. That worked but the color was off. Hope this helps. I work in retail and sell/own the unit so feel free to email
