does anyone know how to secre the 3rd brake light better (the one on the rear deck). I have a 93 max and for the past few months i had to replace the bulbs there about 1 a month b/c the light has been busting. I'm not talking about burning ou the light, i mean they break and shatter. I know it is b/c of my subs in my trunk, b/c once i could have sworn i saw the light vibrate soo much that it hit the rear window, but i was just wondering if anyone of y'all kno how to make it more stable..... Thanx
