The ultimate headlight upgrade H4 (not LED or HID)

They're out of stock at the moment, but you might check BulbAmerica from which I've bought a couple of sets. When they have them in stock, shipping is prompt and they're packed well.

 

Not advised. LEDs are a directional light source in an assembly designed for an omnidirectional light source. With the current LED technology it will never work correctly. You'll end up with an uneven light pattern, dark spots and since the emitters will be wider than a halogen bulb filament it will reduce beam focus and draw the beam in shorter, projecting less distance. Here is an explanation on how halogen bulbs extend distance projection in halogen assemblies:
https://www.philips.co.uk/c-e/au/ca...es/technology/improve-your-lights-easily.html

Basically it comes down to shrinking the light source to increase the focus, and the increased focus then results in increased distance projection. PnP LEDs in halogen assemblies do the exact opposite. They increase the light source size, reduce the focus and reduce the distance projection while also increasing foreground light for worse night vision on top of not uniformly illuminating the assembly resulting in dark spots in the pattern. Do not fall for the PnP marketing, performance halogens will be superior in halogen assemblies.

 

Finally

‘15 Pro headlights. Model was never offered here.

Kindly refer to Post #1 in the thread.

 

Does thar mean the darker housing? How much? Where did you get them out?

Gonna do the ultimate with them or retrofit?

 

I’ve already upgraded to the full meal deal c/w the voltage upgrade & battery. This was the last piece of the puzzle.

 

Thanks for the comments. Sounds like the "drop in" led solutions aren't any better than they were in 2015. I'll try the Osram Nightbreakers in the stock wattage for a while. Looks like the price of admission for a true LED swap is $800-$1000.

 

I still haven't installed my ultimate headlights.

 

You can do it

 

I am. I've got Christmas day, then Thursday and Friday, plus the weekend off, got alot of upgrades and mods to do. 3rd gen trd offroad suspension, arb front bumper and headlight upgrade, gonna be busy.

 

So you’ll be just like everybody else who said why didn’t I do this sooner. That’s all.

 

Probably so. Hell I've had the wiring harness and bulbs for probably a year now. The bulbs are the 100/90w osram's.

 

A year??? Install that for this winter, wiring and bulbs doesn’t take long at all, you’ll immediately question why you waited so long.

 

I have at least a dozen mods to do, many of which would take less time, including aiming headlights. Going on multiple years. No shame from me. Life gets busy sometimes.

 

I took my bulbs and harness to work with me and did them during my lunch hour in the parking lot. I had time to eat after.

 

I like your style! Modding the truck on lunch break.

 

I did this mod a few weeks ago, and I just completed my move across country and I’m super glad I did this before I moved. This upgrade is insane, I can actually see at night and the brights are dang near as good as my diode dynamics lightbar in my bumper which surprised me. Also when A holes are driving with their brights on when I return the favor they cut that crap out real fast

 

Used a restoration kit on my stock assemblies on Friday, installed the harness and adjusted the cutoffs yesterday. Haven't driven at night yet, but they were noticeably brighter this morning. Installing the harness was easier than I expected. Highly recommend buying it if you want to do this.

Update: Drove last night, was initially slightly underwhelmed by the performance difference until I turned on the brights. Huge improvement
