LED lights

No recommendation but a point to consider.  I run them on my JPN Commando as the twin headlamp set up with halogen is bit hungry for amps and in fairness not that good a spread. 

I "upgraded" to LED which reduced the load on the alternator and the lights were bright,  way brighter than before, but the riding experience was  poor.  The light scatters everywhere, no  defined spread of beam and the back reflection from signs and  other reflective objects   increased the contrast from dark to light so much that it was a job ride to the range of the beam  as it was like a black hole beyond the effect of the lights. 

I have not reverted back as the outlay stings a bit still, but I have to come up with an alternative solution of piercing the night sky without having to wear sungalsses!!!   

Pity they don't make a warmer light colour type of bulb...

Just a note to consider.

LED's are coming on in leaps and bounds, a few years ago the beam spread was too much, great for daytime where you want scatter so you can be seen from all angles but not for you seeing where you are going at night. I bought some 2 years ago and they have the tight beam, good enough for the MOT tester to comment as no LED had passed before. No doubt they are even better now.

I wrote the article - any questions please ask.

Andy's bulb looks very like the one I bought 2 years ago, got it off Aliexpress and bought 2 for the same price as Paul Geoff charges for 1, they are now down to £11 ea. As Andy's write up says you have to go H4 reflector but polarity is not an issue as they are wired internally to take -ve or +ve earth. As its 2 year old design even better ones will be available.

Surely.. the wattage of the LED is much smaller than the old incadescent lamp. And the lamp was much worse at turning power into light and thus made a lot more waste heat. So the heat sink on the LED is there to protect the LED and its electronics. It cannot give off more heat than an old-fashioned lamp. If it overheads, the relatively costly LED might suffer, but the lamp shell must be better off.

Maybe that's the issue... the old bulbs get hot inside the big space between reflector and glass, and the LED get hot in the small space behind the reflector? So might cook the wiring...

The heat from the LED is less than from the Halogen, and with the LED fan running its spread rather than localised.

Hi anyone used LEDs for indicators etc? Are they a straight swap with the old style bulbs? Having indicators fitted to my '72 750

Hi there Nick

For Tail/Brake light I did a straight swap with a bulb from Paul Goff.  There are also even brighter/better LED light boards.

For indicators - bulbs are a straight swap but you'll need an LED 'relay'. LED bulbs will not work with the standard item.  I used the one from Car and Classic LEDs which works 'as is' https://www.classiccarleds.co.uk/collections/indicator-relays-electronic

Hope this helps
