The cable that runs from my front dynamo light to the rear has snapped in quick succession recently, the little section between where it exits the mudguard and the light mounted on the carrier. Can't imagine what's causing it to snap here.
It's too short to rejoint now, so needs replacement. Can anyone point me to a more durable 2 core wire please. Think it's 20 AWG, but can't be too thick because there's a conduit that runs inside the mudguard that it needs to route through.
Cheers.
Get normal thickness wire and just reinforce it with electrical tape at the spots it is wearing
When my dynamo cable did this I put heat shrink on the wear point of the old cable.
Ie where there was a cable tie or other friction points. The new cable lasted longer than the dynamo.
Silicone insulated wire is flexible and is usually made up of many very fine strands of copper. This type of wire might cope better with the vibration.

Cheers all. It's not wearing through, it's snapped. First time the wire broke off the crimped connector which was well covered in heat shrink and firmly zip-tied to the light bracket. This time its broken one core just where the two split before the connectors. I can't understand how it's got tugged.
Anyway, I think I will try some silicone insulation stuff, with a decent loop of strain relief. Ta.
Not what you asked for, but I've replaced all the wire on my commuter with stuff stripped from household flex. No more issues with cables getting damaged and I think its actually reduced the speed/threshold at which they stop flickering and reach full brightness. There's one steep hill on my commute where they'd dim and then come back up unless I put some effort in, now they just work.
Standard 3A flex is 20awg, and would be quite a lot more copper than the bellwire that comes with most dynamo lights. But I just used 13A stuff.
Light weight co ax works nicely, advantage being its all happening in one cable so strong and neat. Use the shield as negative and core as +.
