Hello guys, I was trying out some LED's but haven't had any good results currently, I purchased some from Halfords in the UK and they seem to stop working after a short while of being installed, has anyone on here any other experiences with these or are there a certain type of LED you need to buy?

I would guess that your not-so-modern scooters' electrical systems are not regulated at 12V DC, or may even be AC, which would play havoc with LED lights and your SIP digital speedometer that you mention in another topic.

Perhaps if you say which of your scooters you're working with, someone who knows more about their electrics will chime in.

Good luck!

yep...you need to buy AC LED's or convert to full DC.

I have gone both routes and while the full DC system is somewhat better (no flickering), swapping to AC on a batteryless bike also worked just fine with the right bulbs.

Install a regulator if you don't already have one and then it's just a straight bulb swap. You could probably even get away with not having a regulator if you bought 12/24v bulbs, but I haven't actually tried that.

If you do the 12v conversion, I've had success with Pilot LED replacement bulbs. I've had them on my ZNEN since 2014 and not lost a one. Look like this :

Lights snap on and off like you'd expect and they are super bright. They make my amber indicator lenses almost look white. Big improvement in visibility.

They make many direct replacements for standard bulbs. I picked all of mine up at Auto Zone, but you can probably get them cheaper online.

I have converted to LED except for my headlight. Everything else on my bike is 6v DC. I got indicator bulbs from superbrightleds.com, but they did not carry the right ones for my tail light. I ended up getting those from https://www.classiccarleds.co.uk/ after emailing them to ask their recommendation. They were very helpful, so since you're in the UK I would try them. The quality of LED bulbs varies a lot, so it pays to buy from someone who is known to carry good ones.

As others have said, if your bike is AC and/or unregulated you will need to figure that out and then get the right components.
