We saw these @SEMA and was very impressed, Holley sold out the 1st production lot but we were able to procure (4) Classic White 5.75" pieces. We installed these in our 70RR, after I made a Y connection harness so both pair of LEDs would be switched simultaneously to high & low beam. The LEDs fit perfectly in the RR buckets, and total install time was about 45 minutes. To say the least these LEDs are most impressive, very bright with a wide light dispersion. Yes, they are pricey but IMHO well worth the $$.

Just my $0.02...

How are they for oncoming drivers ? IE: blinding or normal

Normal...
Their dispersion is lower and wide...
I compared their output to my standard OE headlights against the garage door, about the same height but wider and brighter.
To date only been driven @ nite 2X times but no issues from on-coming traffic...

Just my $0.02...

So there's no separate lo/high - high beam bulb? I see three 5.3/4" bulbs, yellow, regular white and bright white, all with three wire connections.

The LEDs are low/high, there is no high only LED.
For my setup, I fabricated a "Y" harness using (3) prong H4 connectors so each pair of LEDs are wired in parallel..
So (4) low beams or (4) high beams, but the low beams are pretty bright I don't see using the high beams very much..

Just my $0.02...

Thank you, I just wanted to be sure I wasn't missing anything.

Sinitro - nice upgrade, thanks for the review.

I am running GE Nighthawk 7" LED headlights in my 51 Plymouth. A vast improvement over incandescent or halogen bulbs, expensive and required converting to 12v negative ground.

One issue though, they don't get hot enough to melt snow or ice off of them.

thanks for the reply
