That's the thing though, spider style bulbs don't use the reflector housing as well as the stock bulbs or the bulbs I've tested over the years to achieve a higher light output. If someone rear ends you and says they couldn't see the brakes that would suck. I always strive to improve brightness in my mods, not take it away for some looks. No offense meant by my post, just letting you know there's better units out there for better reflector use and brightness compared to stock.
