Technical Replacing halogen bulbs with LED ones

[jimboy]

Come lads! it's only a car forum. As I've said on numerous occasions, THE BIGGEST MISTAKE ON ANY FORUM IS TAKING THINGS TOO PERSONALLY.... Of course avoid the forum when you've had a few sherbets...:nono:

So I bought some cheap H1 par of eBay and they suck. Does anybody has LED headlights bulbs in their Punto? If you do what bulbs did you use?

I did a month ago (and posted the link to the aliexpress item I bought) in the LED Headlight guide for mk2/mk2b section.

The fact is that changed my night driving experience : try it !
For 30 euros for 4 LED bulbs, it's a real good bargain even if you may fail the MOT (don't care : just put the halogens back in to pass it).

Not legal in the UK so hardly anyone will advise you on this.

There are a million cheap Chinese versions but there is no guaranty that they would work properly, last or give you the correct beam pattern.

I've tried these and I am very satisfied.

As usual you’ve jumped the gun. No where did I say ‘approved’ or make any reference to ECE37

The comic stands in "ECE" : you may not wonder as you are "brexiting"

You can buy extremely high powered LEDs from a major manufacturer to replace normal bulbs and they do claim to maintain the beam pattern, however that have a far higher light output than would be approved for ECE37 these are made only for off road rally and race cars.

In essence there is zero point in making an LED bulb that would meet ECE37 criteria as it would be no brighter and no better than a normal bulb, but it would cost a whole lot more.

However the op is not in the U.K. out lighting regs for LEDs is limited by our own old laws on car lighting from the 80s, I have no idea what the laws on these things are in other countries, yes they have the same ECE37 rules as the rest of Europe but I don’t know what’s else is allowed under individual countries own laws and so advised accordingly.

In France, there is no trouble with LED bulbs installed in place of "regular" halogen bulbs, according that the beam is tested during our MOT (« contrôle technique » in french) : if the LED bulb is poorly designed, it will fail.

The whole regulations on these things is a farce anyway, my understanding is that to meet the regulations the bulbs are allowed something like 0.2mm of variation in the location of the filament in order to get the correct beam pattern, where as most bulbs and manufacturers, submit known good bulbs for testing and approval and then churn out a million bulbs with little consideration for quality control as that level of accuracy costs quite a lot of money, so most cars on our roads might have e-marked bulbs but they would never past the required tests if they were ever tested.

Not to mention the state of most car headlight surfaces....


I will post in the LED headlight guide pictures of the beams of my LED.
(The fact is in "low beam" I never got signal from other drivers i would have been dazzling)

I've tried Censored and I am very satisfied.

Regardless of passing the CT or not getting stopped these ARE illegal in France and the rest of the EU. The laws of physics also apply in France so as there is no light from the side of these they cannot give a correct pattern.

As a physics teacher, I can say you are wrong...
