I created Piston Slap as a way to bring the diverse knowledge base of your favorite car forum to the autoblogosphere with easy to digest weekly posts. The only problem is when a mistake gets published, the thread never comes back to page one with its correction.
I screwed up, so here I’ll do my best to fix it: I was mistaken about aftermarket DOT/SAE approved lights being just as good or better than original-equipment factory parts. Some of the aftermarket parts are promoted as being “CAPA certified” (Certified Automotive Parts Association), but as we shall see, that doesn’t mean what it sounds like, and it doesn’t help with our reader’s query that started the conversation in the first place. As seen elsewhere, parts not up to spec can have tragic consequences with little recourse for victims.
