Bump!
I been doing a lot of research on LED bulbs in the stock halogen housings. I read that these SL1 LED bulbs from Diode Dynamics are designed to place the diode exactly where the filament would be in a halogen bulb, and therefore producing the same reflection out of the housing. Except with much better LED light. So I bought some.
Overall, I can say they are a HUGE IMPROVEMENT over stock halogen bulbs. They are a nice daylight white color, and much much brighter. Like I can actually my lights on the road now. Lol.
I've only had them on 24 hours, but as of right now I can say I am very happy with them and they are definitely worth the money. I know LED bulbs don't have the best reputation for longevity, so I'll post an update down the road about that, but at least they come with a 3 year warranty. Hopefully I get several years of good use out of them and then I will gladly buy a new set.
On to the pics...

In truck, pointed at neighbors house. You can see the cutoff line and how there is almost no glare up above the cutoff line

10/10 would recommend. Best option for sure without changing housings. Let me know if y'all have any questions.
