Brake Light undertail Mod how do I...

[TorontoBusa]

I'm installing an undertail, a "Free Street Design".

I have it connected, and wehn applying the brakes, they are slightly brighter, but no comparison to the original. Is that normal? How bright are yours? any tricks to connecting them (looks easy, but you never know!!)

I want cars behind me to know that I'm stopping, so if this is the norm, I'll modify the stock light into the tail.

Any idea's??

I have a picture posted:

PM Icemann he has aftermark LEDs that you might be able to use or maybe he'll know where to get something that will be brighter than what you have now.
