And not the cheap small ones that barely make a light glow but the ones with the big cooling fins and/or cooling fans...

Cue Phutumsch..

As far as I'm aware, LED headlights require a totally different lens and reflector system to allow the light to spread and focus correctly.

 

A flip of the problem when using HIDs in old reflector headlights. That causes glare and poor spread, whereas LED bulbs will just cause poor illumination without the correct reflectors.

I have these fitted for my main beam, they are white, instant and bright enough for flashing but on a dark country road offer nothing extra than my HID dipped and HID fogs. It also involved chopping away at the housing to get the blasted things in as they're chunky, I have this worry with the led fan ones and clearance at the rear.

 

 

The above bulbs are supposed to be approx 2000 lumens, the internal fan led ones are supposed to be double the light output, if this is the case then fine.

 

I have bought cob bulbs only recently and have been disappointed with them, then there is the concerns what Mondo as stated and as i think this applies less for the mains as it does for the dipped, i don't know whether to give them a go, certainly in my case for the main beam as i do seek an incredibly bright, instant and white H1.

Ha!! Sure aren't you our resident lighting specialist:thumbup:

I want bright white light to. And a friend of mine recently purchased some new headlights for his scion and they came with led bulbs, with big cooling fins on the back. He was well pleased with the light output, bright white light, same light pattern and spread as stock halogens. So that got me thinking. Cause I have considered xenon but that means adding additional wiring so the low beams always stay on.

Leds can go on/off without trouble and always have 100% light output immediately.

Most of what I have read puts these bulbs somewhere between a halogen and a xenon bulb.

 

Here's an American who tried it,

I don't think there's enough room behind the headlight for a led bulb of this type in the high beams?

Could do nightbreaker bulb or something like that

I ordered a set from eBay, got them today.... Didn't fit.... Just barely fouls on the lip of the rubber boot. Also fouls slightly on the metal clip holding the bulb in.

I have one spare light so I'm gonna find a way to work it out. Gonna compare a stock halogen versus this before I commit so I know if it's worth it.

But it is blindingly bright, easily outshined the stock halogen just as it was lying on the radiator connected to the headlight wiring...

I took the spare headlight housing, removed the bulb holder and stuck the bulb in there so I didn't have to cut anything yet. I was more interested in just seeing the output of these bulbs...

Hence the halogen is lower than the led since it's sitting on the car and the led light is sitting on top of the radiator. Also my spare headlight was a RHD while my car is a LHD if you're wondering why the cutoff is so different.

Thoughts: First of all, bright! But by no means do I believe these are 4000lumens per bulb.... It seems more like in the same region as the stock halogens but with more white light... Maybe best case they're slightly brighter, it's hard to tell with the naked(and my untrained) eye.

Second: The hotspot seems more sharply defined, don't know how that plays out on the road though as a positive or negative.

Might be an option if you want that xenon look but don't wanna retrofit(which doesn't work out anyway on a z32), or fit a hid pnp kit(which also adds more wiring on the zx 'cause the lowbeams shut down when the highs come on)
