2 burnt-out idiot lights

I have 2 burnt-out warning lights in my dash (88 vert). I can't find any vender near me that carries a replacement bulb. I even checked with radio shack, but no one has bulbs of that style or size. Mazdatrix has something that looks like what I need, but has a white plastic piece at the base instead of the black plastic pieces I am looking at (second item down, below the logicon) Is that what I need? I don't want to have to pay $5.67 each for lightbulbs. Tiny, tiny lightbulbs.

Well, I care, or else I wouldn't ask. I don't mean to be rude, but you know? C'mon. I have swapped the "washer fluid" and "door ajar" bulbs into the burned bulbs' places, but I would like to have a fully-functional warning light panel.

I'd like to know also.

I'm sure Icemark knows.

The bulbs for Logicon and warning cluster have different part numbers, so I wouldn't guarantee they're interchangable.

When my Logicon bulbs blew I bought two bulbs with flying leads like these that were the correct wattage. I removed the old bulbs from the plastic base, stripped the insulation from the new bulbs' leads, inserted the bulbs into the bases and used the bare copper wire to wrap around the base the same way the old bulb did. They worked fine. Once you get them apart this should make more sense.

I only did this because it was a Sunday afternoon and I need the car back together that day. If I'd have more time (and the warning cluster is obviously much easier to get out) I'd have looked for the real thing. Mazda's part number is FB02-55-431 if you want to try them.

Oi! What the crap? That link looked like it had what I needed. Then, I see that they only ship to New Zealand. What's that all about? Thank you for your insight, though. That's what I was trying to find at my local Radio Shack, but they don't carry bulbs quite like that.

It's an Australian company, hence the limited shipping.

I'm sure you can find a local supplier of something similar. From what I've heard you can do a lot better than Radio Shack. Plus there's always Mazda.

Aww, screw that. I am not going through a dealer to try to find a pair of 20-year-old light bulbs. Jeez, I think I might a have a catalog lying around from some kind of electronics supplier that has all kinds of special-use stuff like these little bulbs. Hmm, I just have to find it, now.

An idea the voltage that goes through there? I'd be interested in putting in LED's.

I guess I will have to get a multimeter and find out what kind of current is running through the control panel on start up for each bulb

12V, just like every other light in the car.

Personally I don't see the appeal of LED's. You're likely to end up with a dim display with two bright spots.

If there’s no bulb, there’s no current. The stock bulbs are 1.4W. The bulbs I bought were rated at 0.1A, so they’re about the same (12V x 0.1A = 1.2W).

ive used leds as replacement with a 330 ohm resistor and it worked just fine for me.

I would replace them all with LED's, not just 2. Just two would look retarded. Anything to make them easier to see during the daytime would be nice.

Hmm, yes. I failed to realize that. It's been a few years since high school physics. Well then, just as soon as I get this PITA clutch slave cyl replaced, I will look into getting 10 or so little 0.1amp LEDs. Thank you for your input. It's always nice when an internet forum can respond to a newbie's questions without fire and brimstone.

Yeah, LEDs have come a LONG way recently, they're bright, and there all all kinds of configurations, color temperatures, diffusion options, etc. The FC3S monitors the bulb voltages though so you need to match the impedance of the incandescents. Hence the 330 Ohm resistors. But wiring these in can get quite tedious.

You want the new generation of high power LEDs, you can tell by their price and integral heatsink design. Below you see conventional "super bright" automotive LEDs, High Power LEDs, (yellow), and hybrids...



(That's the back of the FC3S gauge cluster in BG, where the high-rev buzzer defeat screw is found. Not that you'd want to defeat it...)

If you're buying a bunch, buy LEDs direct from China on eBay.

FWIW, while I had the center trim bezel off I noticed that the lights I thought were burned out on the Logicon would light when I squeezed the Logicon case. Odd that.
