So almost a year ago, I decided to get a pair of 7443 tower LEDs from superbrightleds.com to swap out my tail lights. However, every time I would go to step on the brake they would keep blowing the 10 amp fuse under the hood that controls the vsc, abs, shift lock, and brake lights.
After some troubleshooting, as well as bouncing ideas off folks here on Scionlife, I learned that our car has sockets that are designed for CK-type
bulbs. These bulbs have a different wiring scheme that allows them to function in our car's sockets.
Thus far, there aren't many vendors that offer these CK-type
bulbs. The two vendors are:
bulbs are sold explicitly on their website and are relatively easy to find just by navigating through the bulb categories. V-LEDS make a solid product and I have their LEDs in my license plate lights as well as parking lights. However, I find $80 for two bulbs to be very expensive:
With the CK-type bulbs from V-LEDS being very pricy, I decided to go with a pair of 16-LED towers from autolumination.com. The pair cost me $20. Their site is a bit more 'raw'...all of their 7443 products are listed on one page. Currently, they only explicitly list one model as being available in CK
. However, they do offer other models in CK
as well...you will need to email them to get the lineup of available CK
models. They are good about responding to emails and will gladly help you find the bulbs you need. Just simply ask them which bulbs they offer in CK-type
. They'll then give you instructions on how to order the CK-type
bulbs from them.
There is one other option for those looking for something a bit challenging, or those that really want a set of 7443's that aren't offered in CK
. You modify the wiring of whichever 7443 bulb you choose so that it will function in our car's CK
sockets. Look here for Scion202's DIY:
tC -> FR-S.....and I am back!
Moral of the story...unmodified, standard 7443 LED bulbs will cause our car to blow fuses. You need to purchase CK-type
bulbs, or modify the standard bulb.
