Hey y'all,

First post here.. please be nice! I've been reading what seems like every thread on this website looking for replacement LED headlight and fog light bulbs. I am practically sold on getting the Nighteye bulbs that @Dammit and @SlowFosho have raved about for years. My question, therefore, lies here:

Now in late 2019, the old amazon links to the Nighteye bulbs are "unavailable". I have figured out that Nighteye seems to have been changed to the brand name Novsight. But, when searching amazon for "Novsight H4 LED bulb" I find multiple results that are extremely similar to one another, and all seeming to be from the same NOVSIGHT seller. If anyone can provide an updated link for the LED bulbs, it would be greatly appreciated! I just don't want to purchase the wrong ones, whether it be 50W vs 65W, 8,000 lumens vs 10,000 lumens, etc.

Thanks so much for your input! Hopefully an updated link will help more than just me for anyone looking for an upgrade.
FWIW, I drive a 2016 EX. Thanks again ✌

I replaced mine abouut a year ago in my 2018EX. It took about 5 minutes. They are Nighteye brand and they are 8,000 lumens and 6,500 K color. They work well .They are H4's The Amazon # is A315-H4-25W...They are both hi & lo beams. I think the #'s may have changed

Thanks!

Two questions I thought of:
1. How is the cutoff of the beam? Do you notice a drastic difference, whether it be better or worse, than the stock halogens?
2. Do these work well with the DRL function, dimming the bulbs for the DRL?

I found the (probably exact same) bulbs under novsight on amazon with almost identical specs for a little more expensive yet more reviews. Do you think there is any difference or worth in spending a few more bucks for peace of mind with the better/more reviews?

The beam pattern looked the same to me.....the DRL function worked fine. A year from now, $5 won't matter either way

Has anyone noticed a difference with the amount of heat being generated by the LED bulbs having an adverse effect on the head light housing (discoloration, melting, etc)?

LEDs themselves generate less heat than halogen bulbs. Heat is also generated by various chips on the circuit board.

Some or most of that heat is absorbed into the circuit board and the metal housing used to hold all of it together.

Most designs incorporate a heatsink on the back side, that usually sits outside of the headlight housing (roughly where the H4 pigtail from the car's wire harness usually sits). Whether its by an active fan or just passively, it releases that heat there.

In short, the issue with LED headlights is actually the opposite... where it doesn't generate enough heat in the housing during the winter to melt the snow/ice sitting on it.

So are HID the ones that melt the light housings in some cars. I have Morimoto in my Ram Ecodiesel and they have built in fans to cool them...

HIDs should also run cooler. Both HID and LEDs generate light differently from halogen bulbs. HID and LEDs get their light from an actual arc of electricity (metal "salts" are used in HIDs to help maintain the arc and color), but a halogen bulb actually needs a piece of wire filament to heat up (via resistance) until it glows and that is the light that comes from it.

I gone through multiple LED and HID kits that all ran cooler than the halogen bulb.

The one time I had something overheat and actually melt the H4 pigtail was a halogen bulb that used a filter to produce bluish-white light. To overcome the filter, it generates more resistance/heat to produce more light.

Are your Morimotos LED or HID? I haven't seen any of their HID based kits (or anyone else for that matter) use or otherwise require fans. Their LED based kits use fans just like others due to the circuits/components.

There is a lot more to say about headlight types. LED headlights last longer than HID's and about 10 times as long as halogen bulbs. A gas usually is what gives off light with HID's. A diode is what gives off light in a LED bulb....not wires. A common problem with HID's is that they often take some time to "warm up". A HID headlight often gives off a lot of "glare", and often draw more power

Morimoto are LED lights I did lows highs and the complete fog kits...

The light put out by the LED is a higher color temperature so it may seem brighter. The main issue with after market LED lamps is when you have snow and ice, traditional halogen or HID will put out enough heat in the lamp housing to melt the snow and ice buildup, with drop in LED, the ice will just build up.

Actually, having used HIDs... they can also suffer the same issue as LEDs when it comes to heating up the housing to melt ice/snow.

But the reality is, its still the driver's responsibility to clear snow off the headlights when there's any build-up of any kind.

Pure ice/snow can melt away when it's only barely freezing, but road splashes usually contain at least rock salt, if not mud and other debris. That "crap" won't go away just because its hot enough to melt ice/snow.

And in even colder climates, the temperature can still drop beyond what a little halogen filament can ever hope to overcome on an exposed to the elements piece of plastic or glass. Going back to, driver's responsibility to clear the headlight, regardless of what's lighting up your way.

Well, spent 5 hours on the road yesterday driving through NY state to get home and half way I stopped and the entire front of the car was covered in a brownish ice sheet about a half inch thick. took a bit to get the lights cleared off, didnt want to use a scraper. hitting it with gloved hands would crack off pieces and was able to clear off before finishing the trip. You do have to remember to look.
