OK so I made a mistake but I think I can redeem myself. My lights did not operate the way I stated before. They actually work the same way that everybody do. So I apologize for that.
After looking over the wiring diagrams, I think I have a solution to disable the high beam bulb DRL function while keeping the high beam. I also have a way to keep my new LED strip illuminated at any time the car is turned on.

What other variations were people wondering about? I want to try to help with this.
Where is that DRL Control Module? (E254) in the D1 headlight system diagram.

I actually had a suspicion that this was the case all along and you were just confused. I found it very hard to believe that the previous owner would go through all the trouble of disabling factory DRLs yet keep the rest of the car stock.

Good luck with the mod.

It general, if you see bad life in these bulbs, it's because your voltage is too low. Believe it or not, your experience would have been even longer life had you not been using them as DRL
In my case, the IPF high output bulbs did not fail me prematurely. I merely swapped them out to replace them with the LEDs. Considering that I've used them in the Mazda3 and the Kizashi, their lifespan is rather impressive. I still have them in a box.
As for my Legacy, I gave the car to my brother with the Silverstars in them.

Regardless, these bulbs have a shorter life than standard halogens, regardless of DRL function or not. I can imagine the DRLs usage would only go to reduce their already shorter lifespan. However, these high output bulbs work fine as DRLs and actually output more light as DRLs.

Thanks for the follow up. The DRL control module is under the driver side dashboard, on the left side. I saw a diagram showing it; I'll post it here when I'm on my computer

The wiring mod I want to see is how to make the fog lights on all the time instead of only with the low beams.

I think I have the following figured out based on the wiring diagrams: Just need to do some testing to confirm and I will follow up.

- Run LED strip at all times the car is on.
- Run Fog lights at all times the car is on.
- Bypass DRL control module to eliminate DRL function ONLY.

I just dont like the look of my LED along with the DRL. Also, it is currently wired along with the DRL at the lower voltage so the LED is dimmer as well :( Going to change that. Also, I found out the voltage between the DRL and High beams is only a difference of 13.9V to 14.25V however, there must be more going on there because I'm pretty sure 1/3 of a Volt will not cause the light to be THAT much dimmer.

DRL bypass has been done but I'm interested to see how to do the first two

Oh, interesting. I thought I had read that they lost the function of the high beams as well.

I think it uses a switching power supply to VERY rapidly switch the current on and off instead of reducing the voltage. Most meters would still read this as full voltage.

I guess it depends on how you disable them. The DRL control module is just a glorified relay so anything is possible if rewiring!
