3rd Gen HID vs LED vs Halogen H11 projector headlights

I dont buy your theory.

Agreed, the vision you gain to either side far outweigh the insignificant loss in distance.

 

It isn’t a theory. Here is an interview with one of the worlds top most lighting experts on the mater.

And based on the studies discussed in the link of my last post, the effect is negligable, especially considering the fact that the stock fogs on our trucks arent very bright in respect to a set of aftermarket fogs.

I get the theory, which is all that Daniel Stern article talked about without much data to support his position. However in real world application he doesnt account for the vision gained to either side of the truck which can make all the difference in seeing around corners and avoiding deer and other critters. Also a little foreground light is hardly going to constrict the iris of our eyes in comparison to the headlights of oncoming traffic.

 

I plan on ordering a set of the Philips H9 bulbs for my 2019 Tacoma, but I'm an idiot when it comes to mechanics. I couldn't tell the difference in the pic about what tab(s) to trim down. Could someone enlighten me? I plan on using them for low beam.

 

I have to agree, the Philips H9s are the cheapest way to upgrade the low beams. I did use the adapters and trimmed off the center area to fit.

 

Inside the bulb base, in between the 2 electrical contacts, notice how bulb has plastic tabs on top and bottom between the contacts, and the other just on the bottom. The top tab between the contacts was removed.

 

Ah, thanks. I see it now.

 

I used an exacto knife on the adapters, I just kept scoring them til they went through, I know it takes more time, but the cut is pretty clean and I had no problem mounting the H9s in them.

 

This could be interesting. I’ll see if I can get more info and possibly get a set:

 

Hope you get a set of 2020 OEM led headlights

 

Already have a line on a set. They will be included in this thread once they are available.

 

Awesome

 

So driving on a poorly maintained highway in the rain, I'm starting to miss the HPSV lighting. Not a fan of the LED lighting replacing it. The color temperature seems to make the wet roads look more glossy/reflective, making the faded lines less visible.

 

LEDs are awesome...








Until there is inclement weather.

 

Yep. The high color temp leads to a ton of surface refraction on wet/snowy/frozen surfaces, so you see more glare on the roadway vs the road stripes below the moisture. I very much dislike it. I've actually read an interesting study how LED street lights produce environments especially challenging for older individuals, who have a more difficult time focusing when dealing with the short wavelength glare. Really though LEDs are not the problem, LEDs should be utilized, it is the color temperature of the cheaper blue LEDs that are used that is the problem, rather than using better warmer LEDs for the purpose.

 

Getting ready for a high beam performance boost with KC’s SAE J581 compliant Pro6 Driving lights! Dedicated high beam thread to follow.



(And single on the box means single pair. I was momentarily quite concerned I only received one.)

 

I should really do a build thread to contain all my mod posts that don’t have a dedicated thread.

 

@crashnburn80,

I just want to add my two cents on these Hikari bulbs. I back in October of 2018 I picked up my Tacoma, and started my hunt for LEDs for high and low. I finally found these this Hikari bulbs and have will have been running them for a full year on Oct 27. Through almost all PNW weather conditions these have been fantastic. The only slight issue I have was with ice, not snow. They generated enough heat, to my surprise, to prevent snow build up, but when crossing Snoqualmie pass on an icy night, i did have to stop twice to deal with icing. I was never completely without light, i could just see it refracting(if that is the right word) light in odd directions.

I have had these in super dusty, muddy, and wet environments and never had an issue with the fans. While the engine is on, I can't hear them, but when the engine is off, they do have a noticeable hum if you listen close enough.

For install notes, make sure they are being placed in the house with the wedge in the correct position. If you put them in upside down, the light is all over the place and blinding to others. I did also have to adjust the aim on the housing to make sure it was not an issue for other drivers.

I will say, for having them in for almost a year both high beam and low beam, I could not be happier. Sure I would not mind the new XBs, but the Hikari bulbs have not let me down.

To see you rate these pretty good, makes me happy.

I'll update the post if I ever have an issue with them.

 

Do they have any options for 6500k color temperature?
