Coin door lamps question

[currygoat11]

Well I got an old coin door off ebay. Coin door over 20 yrs old.. nice though!

if the socket is the same, and the voltage is the same that's all that matters. doesn't matter what shape the glass is so long as the wattage is in the ball park and it can physically fit you'll be fine...

from your pic, they look to be the same socket as dashboard lights

[currygoat11]

the #194 at Walmart looked like this:


doesn't resemble my burned out bulb...  (?)

[danny_galaga]

nope. that's called a 'wedge'. you need to find a 'bayonet'. i've forgotten what type. just take one of your old ones to an auto electrician and he'll have the right one to go (",)

edit: i should have mentioned they look like OLDER dashboard lights...

[currygoat11]

Cool okay thanks for explaining that; I can make a trip to Autozone or something tomorrow - thank you again

I found this:

looks like they sell LEDs which are compatible with this older bayonet style socket...hmmm... wondering if I should order those!

A Type 44 Lamp is 6.3V, 250ma.   Applying 12V is probably what burned them out! 

You need either a transformer that puts out 6V (or 6.3V) at 250MA, or if you want to use your 12V transformer, you need to change the wiring so that they are in series, not parallel.

really? okay that explains that!  oh well

change the wiring so that they are in series, not parallel.

The wiring is currently wired in series - that is the 2 bulbs share the same circuit so if one burns out the other one still is lit.

thank you

thats parallel, if they are in series they would both go out when one burns out.

OK now I'm officially confused   I wired my two coin door sockets using one circuit. So socket#1  ground and live) is wired to the PC molex. Socket#1 is also then wired to socket #2 (ground and livewire).

I installed two 12v incandescent bulbs (purchased from an Auto store) today in this fashion. Both lit up and I left the machine on for an hour, no problems. Looked good.

Did I do this correctly?  Thank you again for help.

power scource    this is parallel
   + lead
-----------]----------- bulb 1 +---------bulb 2 +

    - lead
------------]---------- bulb 1- ---------- bulb 2 -

            this is series

+lead---]-------{ + bulb one  -} ---{ + bulb 2 -}-----[lead

[currygoat11]

OK so I think I did mine parallel. The "- lead" is the ground in your diagram?  If so I did mine parallel. That is okay?  Thank you again!

[currygoat11]

Here's a diagram of what I did. Parallel..



This will work no?  Again thanks for your patience as I'm kinda new to this!

Just use what you already have and hook up to the PC's 5V leads instead of the 12V leads.  Mine is set up that way with the 20 year old lamps it came with and it's running fine.

[currygoat11]

yeah well the 6v lamps are now blown, so I bought the 12v from the automotive store hooked up to the 12v PC power supply (like diagram above). Seems to be working fine. Hope I did it right!

Yep, you should be good now.

[currygoat11]

Awesome! Thanks for the replies - I'm glad I got it right
