The ultimate headlight upgrade H4 (not LED or HID)

Replacing the housing is not required for increased light output. It is purely cosmetic. This upgrade maintains the stock assembly with no modifications to the dust cover and completely plug and play.

6000k is really high up there for halogens, the only way you will get that is by having a heavy blue coating on the bulb which will reduce output. I would not recommend getting a halogen bulb in that temperature. If you were really set on it, Nokya makes some 100/90w blue bulbs of varying color spectrum, "cosmic white" 5000k and "artic white" 7000k. These will require the harness upgrade and likely have a shorter life than the Osrams.

If you want a simple bulb only upgrade that increase light output while also increasing the kelvin of the light, these bulbs are standard wattage, but overdriven and product more light than stock. The have just a light partial coating to appear whiter than stock, about 4000k.:
Osram Nightbreaker
Philips Xtreme Vision

None of the above options will perform as well as what I recommended in the original post.

 

I did, however OP seemed to be doing more than what I was looking for. I was trying to find a good bulb replacement only. Unless I misunderstood what he was doing?

 

Awesome, I might have to be content with 4000K in that case. Thanks for the useful input!

 

a straight bulb replacement won't get you significantly better than stock. the bulbs the OP installed are much higher wattage, and require heavier wiring and relays to deliver the wattage they need. in fact, the wiring+relay mods will even improve the brightness of the stock bulbs.

 

Anybody want the harness for a cheaper price? I am selling mine. I used it for 1 day.

 

@mahaloTaco, why did you change your mind?

 

Decided to keep it stock

 

Ground or Conventionally Switched harness?

 

conventionally switched

 

That's what I figured. Thanks.

My son wants one for his 1st Gen, but I'm pretty sure it's Ground Switched.

GLWS!

 

Steve, I'm almost positive that the 1st gen is a conventional switch that you must use your actual hand to turn on the lights.

 

I need to test to be sure but, according to crashnburn80, the older trucks were Ground Switched...

My '04 turned out to be Conventional, but the theory is that was because it had DRLs.

 

If you are concerned on bulb life the 70w bulbs with the harness still provide a nice improvement. Otherwise good but for someone else.

Right, my 03 was ground switched. Theory is that the early DRL trucks are conventional. But test to be sure.

 

I know I'm late the the post but I run the sylvania ultras and I haven't had to buy them in over 2 years. They have a 1 year warranty and they seem to die right before the one year mark so I trade them in under warranty and get new ones.

 

Definitely nice to have free replacement. But the 55/60w bulbs will not come remotely close to the output of 80/85w bulbs.

 

Obviously they won't have the output. As I was reading through the pages on the thread I'd just thought I point out the warranty of the bulbs. I also use warranties for other parts like wiper blades, brakes etc. Call me cheep I suppose

 

My 99 is ground switched.

And if you want to wait, I've ordered an LED headlight kit. I'm going to see how it performs before I decide, but if I like the LED, I may have a harness and 2 85/80 bulbs to get rid of. Just installed them like 2 weeks ago.

 

Unless you ordered the Philips H4 kit that is designed to have proper low beam cut offs, you are likely going to have glare that will require a full projector retrofit. The Philips LEDs look to be a high quality long lasting product, but put out 1/2 the lumens of the Osrams.

 

Thanks. I'm not in a rush. Please let me know if you decide to sell and for how much.

 

The kit I ordered was made by RSI. It was a group buy. Pics from the 2nd gens showed a good cutoff. It's rated at 6000 lumens
