Anyone here install the Alpha Rex halogen headlights? How do you hook up the wiring for the DLR's? Didn't come with any instructions. I've seen video's on how to remove and replace the headlights but nothing on how or where to connect the wiring to the fuse box.

When I ordered the AlphaRex PRO-Series Headlights, I noticed that they did not have any installation instructions posted on there website. So I contacted the Tech Support at AlphaRex. They told me to use the F66 fuse. Which is valid for the 4thGenRams but not the 5thGenRams. After he told me that he did not know which fuse to tap, he said that I could wire it to any 10 Amp - 20 Amp fuse that would come on with the starter.

When I saw that the fuse that was on the pigtail for the DRL's was a 15 AMP fuse I went with a 15-20 Amp fuse. I tested the fuse box with my Multi-Meter to figure out which one I could use that would only turn on when the truck was running. Most of the fuses had power all of the time. The only one that I could find was a F60 Fuse : ECM / PCM / ACT Short Running Valve.

Since this is a critical fuse I decided to use a fuse tap so that the tap was clean.
Our trucks use the Micro 2 Fuse

Here are some pics of the install:

Thanks! Just what I was looking for. Just got done installing the AlphaRex headlights. Got all the wiring done and cleaned up, now I just have to order this fuse tap.
 
I recently had to replace my AlphaRex halogen headlights and found myself navigating the vast world of aftermarket bulbs. I settled on the H7 Halogen Headlight Bulbs, 12V 55W, 4000 Lumens, 3800K, No Glare, High Beam, Head Light Bulbs for Car, Fog Light Bulbs, Headlight Bulb Low Beam & High Beam, Pack of 2.


Here's a detailed analysis of these bulbs and some alternatives, focusing on natural light spectrum, brightness, and safety.

1. Understanding Light Spectrum and Color Temperature

Our eyes perceive light differently based on its color spectrum. The color temperature, measured in Kelvin (K), determines the hue of the light. Lower Kelvin values (2700K - 3300K) emit a warm, yellowish light, while higher values (4000K - 6500K) produce a cool, bluish light.

2. The Alpharex Halogen Bulbs

Alpharex halogen headlights typically have a color temperature of around 3000K, providing a warm, inviting light. They usually have a brightness of around 1300 lumens.

3. The Replacement Bulbs: H7 Halogen Headlight Bulbs

The replacement bulbs I chose have a color temperature of 3800K, slightly cooler than the originals, but still within the warm light spectrum. They claim to offer 4000 lumens, a significant increase in brightness compared to the original 1300 lumens.

4. Natural Light and Human Vision

Our eyes are most sensitive to light in the 550-600nm range, which corresponds to a color temperature of around 5800K, close to daylight. While the replacement bulbs' color temperature is still within the warm light spectrum, the increase in brightness could potentially improve visibility and safety.

5. Glare and Safety

The replacement bulbs claim to have "no glare," which is crucial for road safety. Glare can temporarily blind drivers, leading to accidents. However, it's essential to note that no-glare claims are not standardized, and individual experiences may vary.

6. Alternatives

  • Philips VisionPlus H7 Headlight Bulbs: These bulbs offer a 3000K color temperature, matching the original AlphaRex bulbs. They claim to provide 1500 lumens, a slight increase in brightness without the color temperature shift.
  • Sylvania SilverStar ZXE H7 Headlight Bulbs: These bulbs offer a 4300K color temperature and claim to provide 2200 lumens. They use a patented coating to improve light output and reduce glare.
