Looks like a Slyvania #74 or the lower watt #73

95 Corolla climate control lights not working

Folks, I'm having a hard time finding an answer to this problem. My 95 Corolla's upper console bezel, with the climate control levers and indicators, does not light up. The dimmer dial is working as other indicators brighten or dim appropriately. Behind the upper console bezel is a clear...

Thank you. I just ordered Nanpoku T5 LED Bulbs 74 73 37 2721 LED Bulb Canbus Error Free for Auto Car Dashboard Dash Instrument Panel Gauge Cluster Indicator Lights Lamp(White) from amazon. O'Reilly only has Sylvania 74 in incadescent. No more brown melted prisms and burned out heater panel bulbs for me. Hello to a brighter, whiter heater panel at night, I hope. There are probably other bulbs in the instrument panel of the same size so I will have a number of these in a pack.

 

I usually use Brishine 74 bulbs. They are bright and work very well. Not had any issues with longevity and used them in 4 of my cars for about a year now.

I always use Sylvania LED for 194/168 and for turn signals/brake lights when applicable; but not all exterior light housings are created equal so I have had to compromise for other brands before. Still not had issues with reliability though.

 

I should get an LED bulb for my dome light. The old-fashioned bulb gets hot and has run my battery down once when the door wasn't shut all the way home.

 

LED will still run the battery down, but over a slightly longer period of time; no guarantee you'd still have enough voltage to crank if it sat for a few hours. The wattage will be the same, the main difference is the amp draw. Most of the time, an identical sized bulb will have at least half the amp draw of an equivalent incandescent bulb.

I just swap basically every bulb with LED these days. It looks much nicer and crisper, and the reduced amp draw is nice because it reduces load on the alternator.

 

I believe the LED in the dome light would use significantly less power, so you will be able to accidentally leave it on overnight and still start the car int he morning. It should use much less than half the power.

Another advantage to LED brake lights is they light up right away, like 1/4+ second faster than incandescent bulbs, so a car behind you has that extra time to slow down which might make a difference in avoiding a crash.

 

This is how the LED upgrade looks.. also not a bad idea to swap out your most likely burnt ashtray bulb. They are the same size

 

Are these automotive LEDs dimmable similarly to the original incandescent bulbs?

 

The LEDs I use seem to dim appropriately, though not on the same full sweep of the dial. They usually turn off about a quarter from the lowest setting. However this is just experience from one car. Most of my older cars have broken rheostats so the dash lights are stuck on full brightness, which I can't be bothered to fix since I run full brightness all the time anyway. It's only been in my modern cars that the dash lights get bright enough to glare off the windshield or be bright enough to affect my vision at night.
