Am I wrong in saying they still do not use LEDs for car headlights? Just running lights and indicators, etc. Presumably because they don't work! Which makes it a bit of a scandal that these things are sold as headlight bulbs.....grounds for claiming full refund as unfit for use?
Yes, I AM wrong, newer cars DO have LED headlights! But I posed this query on another website and found that a lot of people had fitted them to older bikes with mixed.....but a acceptable results, eg..
"I have a LED bulb from Paul Goff on my Shooting Star. It is an H4 style bulb fitted in a Wipac Quadoptic unit the beam pattern is very good on dip not quite as good on main beam as a Halogen bulb but with only 20 watts used it's easier on the dynamo."
Suggestion was that there is a reflector depth/bulb design issue here.
