Been thinking about getting my tail light upgraded to a LED one. I see a few posts about how great the BAL light is. I see in the accessories book that HD has a 20 LED tail light. I wondered if anyone had one and could voice an opinion on how bright it is? The price difference is about $60 with the HD being less expensive. The BAL uses only 4 super LEDS just wondering if they are brighter than the 20 HD uses?
