Ive used a Ring LED light as a footwell light in my three wheeler , around £4 from Screwfix ,stuck it on with double sided tape , been working well for 11 months so far , and no need touch the wiring loom
Funny you should say that I say something similar (Rolson) in Halfords yesterday and did wonder about battery life.
