They might be those 60packed bulbs, but all I can say is that LED's ARE NOT brighter than Haliogens as of yet with todays technology. The chip type Led's are the brightest but still have nowhere near the Lumen ouput of Halogens.
I think I know who you are reffering to and I believe the same guy installed Halo's in his taillights which is what produces the brightness, not the led bulbs.
I'm going to school right now for this stuff and it has been talked about in class. I'm not just puling this outt my ***. Had no intentions of rhyming there...lol
Again, LED produces a whiter light that APPEARS brighter, but actually isn't. Still provides less lumen output ofcourse unless there is like 1,000led's per 1 halogen bulbs..duhh..
