Hi guys, I hope this is the right section for this. I recently bought a Vela Discolite dk7000 and it seems as though one of the main speaker lights got damaged during shipment. I have 2 questions:

-The package was insured and sent via USPS. It didn't seem roughed up, and I didn't take any pictures of it. Will i still be able to get money for it when i file the claim? Are there any time limits I should be aware of? The seller still hasn't gotten the number to me.

-I decided to *carefully* crack open the speaker to see if I could easily replace the light. I got this far:

But I'm not sure where to take it from here. It seems like I'll need to get the plastic cover off the front of the cone in order to get to the light but I don't really know how to do it without cutting it out and regluing it, which seems less than ideal. This is my first rehab project so I'd appreciate any advice that you guys can offer! Thanks in advance

I think it's accessed from the rear of the speaker in the middle of the doughnut shaped magnet.

Thanks Super, i got to the light but I am not still not sure how to swap out the bulb...I found a 6v/100ma bulb at radioshack but it seems like its a little bit fatter than the original bulb and also it has a mogul base instead of just the leads....anyone got thoughts on how I could rig this? since it's not actually visible it doesn't need to be super pretty, just functional.

I would find a bulb with leads. maybe replace with LED.
You can find those with leads and they will fit better within that original
tube housing. I would re use that for sure .

bulbs there you can get from radioshack like you did with the wire already attached like the original not sure what voltage you would need maybe 3 or 6 volt ,, led can be used but you need the high intensity ones to be able to see some light behind the speakers it can be done :yes: :yes: :yes:

Did you check to see if bulb is bad for sure or if you have current to the leads :hmmm: Maybe this way you will know what the reason is why they are not lighting ;-)

Hey guys, thanks for the help so far. I found a bulb with leads, but its 6v/25ma bulb instead of a 6v/100ma bulb (thats the one that i found with the mobile class). Will this work? How should I go about this? I'm not sure how to test to see if theres current, don't have a multimeter or much experience with this type of stuff. Here are a couple more pics:

just bumping this cause I want to make sure that I won't fry anything if i put a 6v/25ma bulb in there...btw in that last post I means "mogul base" instead of "mobile class," not sure what I was smoking that night :dunce:

It's fine. It just wont' be as bright as the 100ma bulb. The bulb you have there is called a grain of wheat bulb. Google it and you'll see lots of suppliers. However, 100ma sounds sort of high to me for a leaded bulb -- I don't think I've seen them that high. 25ma sounds about right.

I looked back over the thread and didn't see anyplace where you tested the voltage. I suggest you test the voltage you are getting there to make sure you are using the right voltage bulb. If the original bulb was a 12 volt bulb, I don't think your 6 volt bulb will last very long.

or -- it may last long -- but at 1/2 the brightness
----------------------------------------------------------------------
oops --norm is correct --if you had a 12 volt bulb -and fed it 6 volts -
it would last forever -- but dim

but --the 6 volt bulb with 12 volt power -- will blow !!!

Ira! You questioning my ohms law math? :-O :nonono: :w00t: :lol: :lol:

BTW, It may blow but maybe not right away. Because if the discolites are blinky blinky, then it's getting intermittent surges unlike a steady current flow so it might last for a little bit. Maybe. :hmmm:

En...you'r playing a guessing game. Can't you google the right bulb for that unit somehow or maybe dig up some manuals/schematics, etc? The voltage can be measured but the current draw is dictated by the bulb & that's improtant to get right & at the right luminosity & intensity. Otherwise, the light looks unbalanced compared to the others.

looks shaped like an automotive light to me.
You should compare it to auto bulbs in nearest auto store.
Also you might like replacing all of them with high intensity colored LEDs..
Only problem is getting correct voltage.
