i'm on my second piece of 10mm LED wedge base used as clearance/park lights on the front. replaced the 12volts 5 watts halogen with a 10mm 6 led wedge equipped with 2 resistors in parallel with each other. about 300 ohms as per the color code.
problem: LED was flickering at first. then 3 (out of 6 per piece) leds were out until all are dead.
installed another one thinking it could be the LED but problem is occuring again. replaced the previous halogen bulb and it does not flicker.

Try adding a voltage regulator IC (ex, 7805 - 7805 datasheet(1/1 Pages) ETC | THREE-TERMINAL POSITIVE VOLTAGE REGULATOR IC) instead of resistor. Putting the IC on an aluminum heatsink will also help in prolonging the life of the IC.

i bought one for my dome light.. napupundi isa-isa...
errr.. how do you connect the thingee (voltage regulator), and how much does it cost?

November 8th, 2012 09:38 PM #9Its super cheap sir. Pero 7805 is not enough to power your dome light. 5V regulated lang kasi output nun e. Your dome light requires 12V. Kapag masyado mababa naman yung voltage, mahina output and nag-fliflicker din kapag sobrang baba.
Look for 7810 (10V regulated) if possible. LED kasi require constant voltage and current. Kaunting high fluctuation lang sa voltage, mabilis mag degrade quality niya.

Just bought a 2017 Everest Trend. Has 12,112Kms on it kaya pinatulan ko na for 700K. Only issue...
