Ok, has anyone Replaced the bulbs for the tuner dial and meters?
The feeds are outputting 14 vdc.
I seem to be having a problem finding proper bulbs for it.
Any help would be appreciated.

I too could not find proper voltage bulbs and ended up using four.... 6-7 volt bulbs. But had to rewire them in series for each pair I believe :hmmm: Turned out brighter than when I 1st got box :thumbsup: this is before and after :-D

Not sure what the bulbs look like in the 1M, but here's a site with lots of 14V bulbs.

Here's one that is specifically European

Do you know what the ma rating was on the bulbs?
Why did you use 4 when there are only 3
Did you use only one of the three feeds and wire in series?
Sorry about all the questions but i am on my second set of bulbs.
I used leds first and they blew
Then i used 14 vdc automotive buls that were rated at 1.4 watts
And they drew too much.

There was a thread on S2G a long time ago about someone who didn't like how bright the signal strength meter light was, so he added a resistor to it.

Ok I was wrong :-O I forgot exactly but I ran all three in series for equal brightness and used 3 6v 25 ma bulbs. I used hot lead from one lead and ground from other and just wired the rest from each bulb. Hope this pic helps :thumbsup:

Harder to make look good, because of the spotlight effect

I have to agree on this despite some boxes looking pretty cool with LED's, original lighting has a welcoming warmth about it that LED's just cant substitute.

It all depends on where you position the LED and using light/LED diffuser film. Don't go for very bright LEDs also.

If using bulbs stay within the range of current draw. 

 

I would use LEDs here with a diffuser and see how it looks. Selecting the right diffuser is the key for the good looks and cover bright spots. You can have a good selection of colors too.

 

Over time the heat from bulbs will discolor the plastic back cover of VUs and make them look ugly.
