In early summer 2013 I bought this beat down bicycle, made by NSU (germany). According to the frame number it was built around 1952. The idea was (and still is) to create a bike worthy and capable of towing my red kids-trailer.

This instructable is only about the lights of this bike. There will come some more ibles about other parts of the (still ongoing) project.

The idea here was to fit battery powered LED's into the existing lamps at a low budget. Because when towing a trailer I don't want to spend energy on creating electricity for my lights!

If you're interested head over to step 1 for parts...

Step 1: Parts and Tools

I had two cheap LED-lensers lying around on one side and the bikes old lights, dynamo and a toolbag on the other side. I had no more use for the dynamo, so I sold it on ebay and the toolbag was to beat down (torn straps) so I put it aside.

The lensers were taken apart to get the LED's, the leftovers tossed.

Not pictured: two-wire cable, switch

As tools I used mostly standard equipment. Nothing special here apart from a soldering station and terminal cables: pliers, screwdrivers, side cutters, pen and paper, knife, ...

<p>Nicely done </p><p>This is a fantastic project, thanks for posting and sharing</p>
<p>I've have an old bike light set and dynamo that I was planning on doing an 'ible for, for ages. Damn, you've beaten me to it!<br>Good job though!</p><p> I'm using a smaller CREE LEDs for mine and powering it from some rechargeable 3.7v batteries. I'll post some pics when I'm done!</p>
<p>W&quot;hy not use the dynamo? I have one too and want to add a USB charger &amp; LED bulbs.</p>
wow forgot about this! the project has also sadly got put on hold. <br>I didn't want to use the dynamo as (not sure where you're from) in the UK bike lights are not road legal if they switch off when you stop at traffic-lights so i wanted to do something that would have a battery. To make the dynamo charge the battery would be possible but I needed something clever to stop it over-charging and never got that far. the plan was to carry a spare charged battery and not worry about the dynamo. <br>I should get back on it and get it working for winter! Cheers
very cool use for some classic lamp enclosures
<p>It would be cool to make or get a circuit to flash the rear light at least. It could save on power consumption. </p>
<p>Too bad I don't have an old bike in the garage... Makes me want to build a light right away.</p>
<p>I'm restoring a 70 years old bike in these days. It was used by my girlfriend's granny when she was 15! :D</p><p>I think that a mod like this one can be really useful! Thanks for sharing! :D</p>
<p>Nice, I like that you can keep the look of the vintage lights, but with the modern conveneince of LEDs. Nice job!</p>
<p>good work, </p><p>what about the dynamo?</p><p>u could still use dynamo instead of 9V battery</p>
<p>Dynamo is not stable, it could burn the leds.</p>
<p>there are special led's out there for use with a dynamo, but the cost around 7 or 8 &euro; a piece....</p>
