LED headlamp lamps
« on: 25.04. 2015 11:52 »
I have just ordered a BPF main beam/dipped beam BPF LED lamp that will go straight into the existing A10 headlamp without any modification. If anyone else should be interested in buying and fitting one they are obtainable from here: http://www.dynamoregulatorconversions.com/led-headlamp-bulbs-shop.php Just thought that this information might be of use to some of you.

Please will you post a review here when you've tested it?

hi,
    so if i am reading  the info in the link correctly the led p36d bpf would be the one i need,it also states it is the same bulb for 6 or 12 volts .
But i can only get the option of negative earth and not positive ?yet if i look at the photo of the bulb it says available in both negative and positive versions!

I just checked out the website, and you are correct. Positive earth not yet available yet but coming soon.

In particular I'll be real interested in how you find it works with your existing reflector and lens i.e. its projection on both high and low beams. Thanks for posting.

If you just swap the ammeter wires at the terminals and change your battery terminalsand repolarize your dynamo you will have neg earth. Ten minute job.

I concur, I recently changed my daughters mk1 mini to negative earth and the only difficulty was the fuel pump wiring had to be reversed... took me about 5 minutes all up

Very pleased with the LED headlight. Note no discharge at all on the ammeter. The yellow colour is the halogen bulb, the blue/white is the LED. In reality the Led does not look blue to the naked eye, but that is the colour that the camera sees. BTW I checked with the MOT tester, and LED lamps are not illegal in the UK. You can just make out the ammeter discharge on the halogen lamp pictures. Sorry for the delay in reporting back. It completely slipped my mind.

One of my mates has been testing several LED bulbs in his headlamp.  The general finding is that they are OK round town but if you actually need to illuminate the darkness, you will end up in a ditch very shortly.  They give a pencil like beam, they really need to be designed as a whole unit, not just a bulb with an existing reflector.

Bill, not sure when you looked at the post. What you surmised was right, but I have since edited the post. You should now see 4 pictures.

What post would that be John  ;)  must have looked in just as you posted

Quite impressive, would need a ride out on a dark night I suppose to get a good idea of penetration.
but considering this is early days for LED systems the future could be ......  (no I'll resist)

Thanks for the review tho John
