Cheers for all the info there Henros, i know i'll be giving it a go!

easier than replacing the bulbs all the time!!!

question about setp 8, is that plugging straight into the original socket from the wedge globe? no mods needed here?

cheers again

[hippy]

are those VR resistors?? can they take the power and the heat?? how or where did u get the package to put the pcb on to fit??

[Henros]

Craved, the whole thing will plug straight in, no modes required.

Hippy, they are just normal 1/2 Watt metal film resistors, more than adequate as the power dissipation is less than 1/5 W. I'm not quite sure about the second part of your question. Do you mean the socket sitting under the PCB? That's the original socket for the parker bulb.

[hippy]

yeah that last question was dumb sorry .. i only looked at the pictures .. too lazy too read .. hehe but thats great stuff ... would u know if u are able to get blue/white leds?? like white leds with a strong blue tinge?? or maybe even a pale blue led?

Electronics Noob question here, but why do you need the additional diode when you are using 6 already?

sorry if this is a really dumb quesiton:D

And thanks for the very detailed description and photos.

Bah...

I applaud your effort, but you can just buy these bulbs (with an LED matrix) from Raybrig or other bulb companies right off the shelf and plug it straight in.

No PCBs, No soldering, no measuring.

Autobarn should be able to hook you up, if not, try PD's Car Audio in Hornsby... They had heaps last time I checked.

you got a price on those merli?

Hippy, all white LEDs have a blueish tinge because they are essentially blue LEDs with an internal phosporous coating. The amount of blue various from manufacturer to manufacturer. You can get blue LEDs with different shades of blue. Jaycar for example, sell 470 nm blue and 505 nm blue/green LEDs.

Steve, the extra diode is there to provide reverse polarity and trasient high voltage protection, the IN4004 has a reverse breakdown voltage of 400V. LEDs have much lower reverse breakdown voltage. In reality tho, you could do without it, but you need to increase the value of the resistor as the diode helps to drop around 0.7V which now has to be shed by the resistor.

Merli, construction was half the fun, for me anyway.
