And again, I really appreciate your pics. I like the color these are putting out a lot. Has the connection issue been resolved? You didn’t mention it so I’m assuming you didn’t have to tape anything. Cheers!
I'll get some night pics as soon as I drive at night, havent seen them myself yet lol. Was going to last night but had a serious case of the dont wants.

As for connectors they were spot on for the low and high beam bulb. I opted to use another SL1 for the fog light vs the SLF they have for the fogs. I had to trim up the tab so it would fit (you have to do this with halogens as well if you swap) but the plug on this application had to be reversed. I dont recall what bulbs were having the clip issue (I think it was the high beam) but maybe the fog lights are wired backwards so it would never be right for both? I did not tape...I just plugged and ill see how long it last like that. It was easy to get to that spot if I have trouble.

These things are pretty darn bright at night. Love the color...so crisp. Here are a couple shots of lows with fogs and then high beam no fogs. My camera makes it seem a little brighter than it is maybe but not too much.

I never said the factory halogens didn't have glare, they do and being as now you have a brighter light the glare is even brighter. So you have spent how much on these bulbs to have the same subpar beam just brighter?

DD it's nothing personally, it's just the nature of the beast.

Wayne, you're adding nothing to this conversation other than entertaining yourself. I've had these installed for a bit now and have had zero issues with others feeling the need to flash me. These bulbs are bright enough that if there was an issue, people would be flashing - guaranteed. You have no experience with the product and are making assumptions about their performance. I'm extremely happy with the purchase. It's clear to me a lot of work went into these and Diode Dynamics is to be applauded. If these bulbs were an OEM option I would believe it - the performance is that refined and that good.

Many thanks for the night pics! I think I’ve made my decision. Thanks to everyone for continuing to provide feedback regarding these lights. This site is pretty awesome and I continue learn something every time I come on here.

Heat dissipates through materials... you do not need them to be exposed externally. I know this sounds simple but basically... your factory headlights don't melt, and each halogen bulb puts out 45+ watts of heat (55W bulb, only 10-15% efficient). These are putting around 18 watts of heat into that same space. So less than half of the heat as factory bulbs.

Yes, it's true that LEDs can't take high heat like halogen, so that's not a completely fair comparison.. but it's really not an issue at all. These have been tested in the headlight, sealed, at 185 degrees ambient. We have equipment here that is specifically designed to do this test - it is the same test all factory headlights go through, defined by SAE. They will be just fine. And as I mentioned in a prior post, this is repeatable and test-able... making it more reliable than a braid that will hopefully be in cool air, and hopefully stay spread out, and hopefully not build up a layer of oxidation which reduces thermal conductivity... etc etc.


Thanks.


No issues here. And then engine bay is far from a sealed compartment like the tiny headlight assembly's voids. At least any breeze or driving circulates the air. Been over a year now and still no problems, and run DRL's so they're on all the time

Question.

Can anyone with the SL1's advise of their performance in rain or snow, especially at night? One of my biggest complaints with LEDs is their performance in bad weather compared to halogens.

I was able to install mine just before I left on a 4 hour trip every Sunday night for work. First of all I was impressed with the output at night on the interstate. I could actually see exactly where each light output pattern hits the road surface. This morning when I left at 6:00 it was still dark and raining with dense fog of less than 1/8 mile visibility. I was very impressed with the output in these conditions as well. There wasn't any glare from the fog. I also run my fog lights with my headlights, which are Diode Dynamics XML2 LED's.

YOU CAN TAKE THIS WITH A GRAIN OF SALT, but it's my experience.
I'd leave them the way they are or buy a new set of proper lights.
I did a set of LED into Halogens last year(on my dad's non-F150) and they are a complete waste of $150. Maybe they are the "old ones", but I'd suggest you examine the entire setup IN PERSON before buying anything.


1. The light quality is worse then stock. It's too bright and poorly focused.
2. They are not designed specifically for your truck, rather they are replacements for a series of bulb. So, the unit will fit your housing, but there's no guarantee other parts will mate. In our case, I had to cut the rubber seal to install the unit. It no longer works. It's only a matter of time until they get wet and fail.
3. They are very deep compared to the stock bulbs and are difficult to install. I had to remove the battery to get the unit in and the installed unit is right up against the battery now.
4. They have bulky wire harness which has to be stowed and looks sloppy.

Good luck whatever you do,
TomJV

1.) focus issues with LED's will always be a problem since they aren't perfectly shaped, but having had mine in for a few weeks i can tell you it's inconsequential on the SL1's, there's some streaks in the focus but it outputs more light further with pretty well focused hotspots near the cutoff and absolutely lets me see better than the stock halogens which just are not bright enough period.
2.) you have to cut nothing for these bulbs they twist right in and install without issue, if you have an older model with Kree led's or something i could see this being a problem, but that's your fault for not researching why these LED's aren't good for headlights.
3.) These are deep, but still fit behind the stock dust cover perfectly fine and nothing needs to be removed
4.) A driver is just part of any LED setup. Unless they put the driver for the LED's at the ECU it's always going to be there to output consistent current.

All in all, i think you're comparing apples and oranges (not that they can't be compared, but since these seem to be different bulbs you're talking about they produce a different result)

So wait, your review isn't even for a F150?? Am I on the wrong website?
