Just a cheap alternative & easy to install.
I bought one of the black Ultrabrights and have been very happy with it. They actually released a white one this week. It on sale this week, plus there coupon code for Buy 2, Get 1 is still working (SUMMERSAVINGS). Just put 3 in your cart, and it will take the price off of one.
My inlaws purchased a few of their basic white ones because of the ease of installation and havent had problems yet. They are actually the ones that gave me the company info. They had 1 defective unit after about a 2 years and the company still replaced it.
I think this white 1 looks good + its brand new, and Im a sucker for new anything:
