just go read the 1st issue of oz sky and telescope, there was a guide to building a redLED torch, just make the resister a bit higher resistance (to make lights dimmer cause you don't want to 'see' by the light) and if you like put on multiple LEDs in parallel like this
Code:
---led---
| |
---led---
| |
---led---
| |
| resister
| |
batteries
that's how I remember led's working anyhow, you might not want to get the superbright led's just get normal ones as you don't want it to be overpowering.
hope you have some luck.
