Rear turn signal bulbs and LED replacements
 

Hi folks,

My driver side rear turn signal bulb went out (after merely 1.5 years of ownership) and I have been unable to find a replacement in the local auto parts stores.

After searching the Web for WY21W (sequence printed on the bulb), I have been able to find one dealer selling such a bulb: http://store.candlepower.com/74amw.html

So, needles to say, I say "Thank you Toyota for choosing a bulb that appears to not exist and is $8!"

This led me to try LEDs in hopes that they would last much longer. I found the following: http://www.superbrightleds.com/specs/7443.htm

These installed with a slight modification to the base, however, I cannot tell if they are as bright as the old bulbs as there is still day light.

More so, since they draw less power, the car believes they are burnt out. To correct this I'd need a load resistor. Anyone know what kind and how to install such a resistor?

Also does anyone have any other suggestions for different LEDs? I think the ones I bough should do. I'll do a compare tonight.

Thanks,
Mike

sounds like $8 is the threshold for aggravation.
gas prices are plummeting, you'll save $8 on your next fill up
it'll be a push

Well, you have to put price in perspective. Eight bucks for a tiny filament based light bulb is rough. I can get a eight 100 watt bulbs for that price from Walmart.

My bigger concern is the inability to locate a replacement.

As one can see from the photos below, the LED bulb is not quite as bright or does not quite fill the entire reflective area.

Left LED, right standard.
Left and right LED.

Update: Found another place that sells the standard bulbs for $2 and they also sell a bunch of LEDs that should be much brighter....

Wouldn't Pep Boys, Toyota, etc. stock them?

I checked the local stores (Napa, Auto Zone, Advanced Auto Parts). I couldn't find an correct type amber one. Haven't had a chance to call Toyota dealer yet.

But, I am interested in replacing them with LEDs. Possibly the front as well.

thanks for taking the time to research and post your findings, I was wondering what is the kelvin difference between the 3 watt and the 3x1 watt.

I have a daytime running module from web electric to replace the standard daytime running lights and all I need now is the right bulbs and instructions on how to disable the standard canadian daytime running lights to be replaced with this combo.

What are you planning on replacing the DRLs with? LEDs?

I have confirmed they have the cheapest so far discovered stock bulbs. About two dollars a piece plus about four dollars shipping. They confirmed their stock bulbs match the wattage of the factory bulbs. One difference is that they are painted glass verse the factory bulbs are colored glass.
