LED H4 Replacement bulbs.
Has anyone fitted LED replacement bulbs to their headlights?
These are not the JW Speaker type units, but HID conversion style items.
I'm aware of E mark issues. Let's assume its for off road.


Cheers

You will not get the correct light spread or pattern with an LED type filament in an incandescent reflector lens arrangement so you will be wasting time and money, assumption off road or not! Plenty of information where people have tried different variations of your proposals on the forum with no success.

I tried it a couple of years ago, with a set of H4 LED's in hella spotlights ... complete waste of money.
Gave no real 'beam' just a bright flood light for about 25 yards ahead. Standard bulbs were way better.
I don't think LED bulbs get refracted by the light reflectors very well [The reason most reputable places say LED's are no good in lamps designed for bulbs]

Don't be a d1kc! I am fed up of being dazzled by idiots that have 'upgraded' their lights with unsuitable, untested and unapproved kit and as a cyclist I am being put in danger because when one of these cars gets behind me I become more or less invisible to other road users due to the blinding effect of the unfocused light pattern.

DON'T DO IT, IT IS DANGEROUS!

Thanks for the lecture.
My plan would be to buy them and get the beam pattern set up/checked at the local garage.
There are newer kits that account for beam pattern. I suspect older bulbs were just fog light spec items.

Cheers

Sorry, I thought you weren't intending to use them on the Queen's highway........

Sounds like you are going to do it anyway, you clearly don't give a damn!

I know what I think.

I don't think the guys were lecturing you, you were asking for advise and they have given it to you. I'm sure the advise was not what you were hoping for.

I have to agree with them - don't waste your money. I'm afraid if you are going to improve your lights you are going to have to invest a bit more cash.

Your original post should have perhaps been worded a little different. Without the E mark they will not have gone through the appropriate approval which you yourself appear to be casting aside. If it is indeed for of road you can do any alignment yourself against any wall. Why take it to a garage? Also you specifically asked for H4 headlight bulbs which would imply you will need to use them on the roads without much consideration for others perhaps?

You are wrong in your assumption as from the quote I posted above these lights were H4s not bayonet. When did you last see an H4 fog light?

I asked it in the manner I did because I'm aware of the storm talk of aftermarket HIDs caused. I'm also aware of the issues re-beam pattern, brightness, self leveling etc etc.

I'm up to speed on the type approval process as I've a background in automotive industry. Specifically the design and production of cars.

I'm simply was curious to see if anyone had fitted some and was wondering what results were gained.
I was hoping for a reasoned discussion on the matter.

It's my suspicion that these will become the new HID replacement. To that end I was considering buying a set and doing a write up.

And Re the fog light bulbs..

Vs

That's from a quick google.

As you can see the top one would be utter tripe. The second one has potential to work but I'm suspicious.

Wouldn't bother with the write up unless of course they're E marked which would potentially captivate a great deal of interest, there is plenty of technical information re: wavelengths etc. in the thread below clearly (ish Laughing) going into detail why LED filaments will not work in normal lights. The thread is also only two weeks old! If there was a cheap, legal LED alternative to standard H4 filaments someone would have come up with it by now. Either way I do not think we'll have to wait too long. I have never had an H4 fog light fitted to any of my vehicles, I have learnt something new today, thank you.

Cetane, why do you want to 'improve' your lights? Is there something wrong with the standard set-up or are you just out to add the latest 'look' to your vehicle. The big problem with higher output lights is that it is great for the user and a huge step back for everyone else on the road, with vehicle lighting more is not always better. If your main beam is a bit poor then a set of spotlights that you can use on unlit country roads are perhaps a worthwhile addition but increasing the output of the dipped lights creates safety issues for all other road users. The effect of driving towards someone with super powerful/bright headlights can be the complete removal of all peripheral vision. The bright lights are perfectly visible but cyclists, pedestrians and street furniture can disappear into the contrasting areas of total darkness that are now created. The legal limit on dipped light output and the requirements for self levelling on HID exists for a reason. Please don't think that you know better and the rules don't have to apply to you, the roads are dangerous enough as it is without adding to the risks.

Speaking as someone that's come extremely close to running over (an admittedly badly lit) cyclist on a road with an oncoming car that had badly adjusted headlights, I would second the opinion that non approved headlights are a bad idea.
At the end of the day, if I had hit the cyclist (I swerved at- and just missed the oncoming car) that would have been my responsibility yet not my fault.

If a headlight is type approved for use with one type of bulb and you don't use that, then it's not approved. LEDs can produce really good beam patterns but they're not the same as an incandescent and shouldn't be treated as such.
