Date: Sat, 12 Apr 2003 19:45:28 +0200 Remember to change the series resistors, and possibly the connection scheme for the LEDs. Blue and white LEDs have a higher forward voltage (about 4 volts) than green ones (2.05 volts). Im the AJBR20 the 4 LEDS are 2 by 2 in series with a series resistor per series pair. So simply replacing them with blue or white ones will result in no light, because the LEDs need at least 8 volts and the AJB can only supply the battery voltage. Red or orange LEDs don't have this problem.
