Can you provide the link for fog lamps you used too ? Rigidhorse doesn't seem to have the right size and there are many leds in the site but I want to make sure which one works. Thanks, |

Suppliers keep changing, but what you're looking for is the same lamp with H8/9/11 base for the fogs. With a bit of searching I found this one, which is available in H7 as well:
https://www.amazon.com/dp/B01N4E9KC2...sp_detail?th=1 I've seen them on eBay and Ali Express too, at better prices, but they come from China, so shipping will take longer. |

I'd be a bit more careful comparing lumens than some people are here.
The USDOT regulates headlights, and limits the amount of lumens that headlights emit. The limits are different for high/low, the measurement methods are weird, etc. For instance, my E46 Xenon headlights (non-adaptive, with auxillary Halogen high beam) is better and emit more lumens than the E9x/F3x adaptive Xenon, which uses the Xenon beam for both low and high. The Halogen in the E46 added more lumens that resulted in reaching the limit for high beam operation (which is higher than low beam alone), giving a magnificent result. Low beam operation (of Xenon) in a single beam essentially/effectively limits the high beam output. (LED can easily add lumens, however.) Since low beam lumens is limited (especially wrt high beam), you should compare low-beam vs. low-beam and high-beam vs. high beam. |

The current USDOT regs date to 2007, so they're obsolete. They even still talk about sealed beam bulbs. Most LEDs aren't DOT approved because the approval process takes not months but years. As a manufacturer by the time your LED gets tested you've probably moved on to the next product generation. As for finding the DOT regs with respect to lumens, good luck. You'll sooner find Waldo. Most of what you can decipher from the DOT regs relate to beam patterns and minimum candlepower measured at 100 feet.

If you want to find some stuff, start at https://www.danielsternlighting.com/ - it will at least get you to the correct area at NHTSA (Daniel has commented vociferously over the years, although he is "retired" now.) Be forewarned: Daniel doesn't abide hosers and opinions, only facts. |

What it boils down to is that where H7 LEDs are concerned you're on your own to figure out what works. I researched them for over a year before investing in them, and my research paid off, because the ones I chose work very well. The first thing I took off the table was any that used fan cooling, as that looked to be a common source of failure. Next was the element placement, which had to closely resemble the filament of an H7 halogen. Once you take just those two steps you eliminate perhaps 90% of what's out there from consideration.

Also, how did you determine the lights are “pure white. No yellow, no blue”? Last edited by kabrichx; 11-14-2017 at 05:56 PM.. |

You have to code out the cold and warm checks, whether you have canbus harnesses and/or resistors or not. The cold and warm checks will cause the LEDs to periodically blink. You don't see it with halogens, but with LEDs you do. It also describes how I did the fogs, low beams and high beams. |

Update: I looked today at the Amazon listing for the headlight bulbs I bought, and they're back again, the price is $59. While there I saw these, which are exactly the same, for $31, so you've got to shop around.

Very. They could have a better pattern, but they're no worse in that respect than halogens, and I'm not inclined to drop major coin on new lamps with projector lenses. I might if I drove a lot at night, but I don't.

I saw some that look the same but don't come with the canbus ballasts. Those are what prevent error codes from showing up, so make sure what you get includes them. |

it's been a couple months, do the led headlights have a better light output than the old halogens?
