Dash Lights Dim!!!!!!!

[vwcvr6 0]

Hi guys i have just changed the window switches, 2 light switches and rear window heater switch with blue led which i purchased from Ultraled

 

the leds i purchased were 7000mcd and they look nice, but my problem is the dash (gauges, mfa Display )since i fitted the 7000mcd leds my dash has dimmed quite alot!!!!!!!

i can barely see it

 

has any1 had this problem, are the leds causing tis and draining to much current for the dash to dim badly

 

(is 7000 mcd 3mm to much)

any help would be appreciated,

Hi VWCVR6, glad to see someone else has also changed to blue. Its quite simple, the angle of dispersion is not sufficient from the leds so although when you look at tehm straight on they seem bright they are unable to disperse the light fully. I presume you have just replaced the bulbs with single leds on the dash. The only way around it (which I will get round to in the summer probably) is to solder about 3 leds per clock (ie 9 in total) onto a pcb and mount this in place of your bulb holders. Dispersion is a mjor problem with leds unless you get the mega pricy ones. Even frosting has a limited effect. BTW, LEDs use almost no current and also do not generate any heat. 7000mcd is low, you need about 15000 (a guess) which you can get from multiple leds and I would suggest 5mm for the clocks anyway.

thanks alot for replying !! i havnt yet changed the lights on the dash they are still standard green!! i have changed only the switches with 7000 mcd!!

after i changed the switch lights the dash (mfa clock, speedometer etc) is badly dim!!

 

is there any reason for this!!

Try turning the variable resistor that controls the illumination up - on the headlight switch. It may have been turned down accidentally. (!!) :bounce2:
