GBC Front Light Voltage?

[HillbillyScientist]

So, I've been playing with modding some old Gameboy Colors for resale, and I've SP front light up and running agian ( I accidently cut the ribbon cable so I had to solder directly to the tiny resistor and led). My question is, Is the 47 ohm resistor even needed. Because, I tested the front light with a straight 3v and it seemed to work fine. Helps appreciated.

If I was in your position I would probably just throw the resistor on there just to be safe. Good luck!

Alright, thanks.

You can actually install a gameboy color frontlight fine with out a resistor if you use this guide:

I did it and everything turned out fine:

That looks good. Thanks!

3v is not what kills the front light, and its actually the correct voltage to light it up. Its the 5v that the GBC uses that kills it which needs the 47 OHM resistor in series to lower it down some.
