Picture of Cateye HL-130 and LD-130 LED Bike Light Upgrade
A very simple how to showing what needs to be done to upgrade the Cateye 3 LED front and rear bike lights to 5 LEDs.

Step 1: Tools and parts

You will need:

Soldering Iron
Soldering Iron Stand
Solder
2x 5mm red LEDs (5000mCd seem about the right brightness)
Small coin (to open case)
 
I was hesitant to mod my tail light because I wasn't sure which LEDs to use. The 5000mCd ones are spot-on! I can't tell the difference from the stock ones. Thanks for posting this, mate!

Hrrmmm looks good! I'm wondering a couple of things, however... 1) Is the power coming straight from batteries with no current-limiting anywhere? Just wondering if all LEDs remain as bright as they should once two extra have been added. 2) Do the light patterns still flash in the same way? I.e. does the knightrider-esque pattern not skip the two new ones? Cheers! Always thought it was pretty poor not to fill in the remaining two holes, but found the PCB sat pretty tight and didn't want to break the thing...

thanx :) 1) the new LEDs are just as bright as the old ones. 2) you know the pause you see when there's no LED illuminated when it's in that pattern mode? that's when these other two LEDs light up! i thought that too. be confident and only pull on the battery clips, not the PCB. use long nose pliers and 'walk' the PCB out pulling on the top connectors, then the bottom, then the top, etc. if you do bent the battery connectors whilst pulling them out, you can always re-bend them. have fun :)
