Are LED headlights any better than the stock halogens?

I don't know about the aftermarket LEDs for Gen 3, but the LEDs on my Prime are the best headlights I've ever had. The high beams are a little too narrow, but they are still way better than HID or halogen.

 

LED's are the best. IMO

 

I bought the Sealight S1 LEDs (non-fan, passive cooling version) to replace the low beams in our 2012 hatchback. Once I unbolted the coolant reservoir on the passenger side, the installation there took about 10 minutes and another 10 minutes for the driver’s side. Although the light is distinctly more bluish than the OEM halogens, they are much brighter and we have both been very happy with the increased visibility at night. As the power consumption of these LEDs is so low, we are also driving with them constantly ON during the daytime also in order to increase visibility to others.

 

I'm very happy with these.

 

This should answer your question

After carrying the 1, all I need a pair of 1.2 gigawatts LED headlights.

 

Is the earth round

 

I have a pair of Hikari H11s in my Halogen projectors.

Yes, the fans are loud when stopped.
Yes, they’re worth it. Bright even beam pattern with a razor sharp cutoff.

Factory halogens were abysmal and I frequently wondered if they were on. These are 90% of the HIDs that my 14 Mustang had.

 

I have been using the Cougar Motor headlights and they have been excellent for 3 years so far. I have a set for the low beams and second set for the high beams.

 

These are whiter at 6500k, chip is external and out of the heat

Do the latest Prii have LED headlights as standard equipment? ff so, that would be a good place to start for deciding what LED replacements to use in an older Prius, no?

And does not the stuck-in-the-past NHTSA have some strict limitations on the permitted light output of headlights? (I think I have read that some European cars have headlights with computer-controlled beam shaping and aiming, but they would be illegal under current NHTSA rules.)

 

The Prime had LED headlights and tail lamps.

 

I've never read of standards for retro-fitting older vehicles. The companies make claims that their product is compatible(voltage and socket), but the shape is going to determine how the light gets reflected forward & with how nmuch splay.Trial and error. Best you can do is try to find an LED that is physically similar to your OEM, and hope the focus isn't crazy off. You don't want to blind oncoming traffic.
