after a few years and several different types of lights where batteries are in bottle cages straped to crosbars under your seat come to thinking must be a better way to do this. looked at the nightsticks great idea but their still bolted on their. Looking at the long tubular design then onday happend to have my seat post out hmmmm an idea. took 1 7.2 volt nicad remote cotrol car batery split it in to its 2 halves solderd back together length wise added connector from old set of lights dropped into seat post add a bar plug to the end to stop falling out and a bit of foam to hold it all still inside no rattling conctor pops out top off stemseat bolts on again. and their we have it lights but wheres that battery???

Seat post used is a synchros hollow straight the way to that top through the clamp.

Clever sod..... May give this a try when the dark nights come round again.....

Did you drill a hole in the post to get the wire out?

the post im using just needed a small hole through one side of the bottom part of the clap as rest is hollow and holes in all over he place just the one on the face against the tube.

Nice idea....

Maybe worth sealing it up a bit in plastic to keep the water out?

how about keeping the theme going you could just slide narrower cells inside the handlebars themselves?? OR fork steerer tube? - less wiring needed.

Really good idea - I've been pondering this for a while. Will those batteries give you enough mAh to do a decent nite ride of 2-2½ hours?

I know you're excited but PUNCTUATION!;)

swounds like a good idea tho'. I hate having batteries on the bike

great idea, but couldnt the wires have come out the bottle cage mounts on the seatube- to save drilling holes in nice shiney seatposts ?

Like the bottle cage mounts idea. But cant see the hole in the post ive got and imagine the faff with gettin a wire in their :) Punctuation?


the batterie is a 3000mah unit.

so far have got hour and a half or a bit more using a 15 watt halogen spot. closer to 3 hrs using a set of smart lights
