I just installed an undertail with two led tailights with the blinker and brake lights integrated. They seem pretty bright, but my buddy that was riding behind me said that he could see them ok when i put them on, but if he didnt actually see me put them on and just came up behind me then he wouldn't know that i was braking. Is this common? I got the undertail on ebay, and the fitment is perfect, but i think they may have went cheap with the lights. They are siliconed in and dont look like they could be easily replaced. Any help with what i could do would be appreciated.
