Questions & Answers

Ask a Question


These LED switchbacks are not error-free.

Will these work on 7444 single-filament socket? And if not do you make any 7444 single-filament switchback LEDs?

7443/7444 socket size is typically dual filament.

It will not work properly for single filament because it needs the parking light + turn signal function. Single filament sounds like it only has the turn signal function. For something that will work with single filament socket, you may consider a product like this: https://store.ijdmtoy.com/products/led-indicator-bulbs-20-052-switchback

This will allow the single filament socket to have 2 functions as the bulbs come with a wire that you will need to connect to a 12V power source such as ACC 12V+ spot in the fuse box or any other 12V power source depending on when you want the white lights to come on.

I wondering if the 7443 bulb switchback need resistor?

Yes, if you plan on installing these LED bulbs for your turn signals, you do need to install resistors to prevent hyper-flashing. You may check out the resistors through this link: https://store.ijdmtoy.com/products/wirng-harness-adapter-aa1037

Will these work on a 2015 Hyundai Genesis 3.8 sedan? Thanks

According to Osram Sylvania, it shows your vehicle uses a 2357 for the front turn signal. However, please physically check your bulb size in your vehicle because Osram Sylvania is not always 100% accurate. 

If it does use 2357, you can select the 1157 option which is interchangeable with 2057, 2357, 7528, etc.

Will these work on 2010 Prius?

According to Osram Sylvania, 2010 Toyota Prius uses a 7440 bulb size for the turn signal. So the switchback LED lights may not be compatible. We would recommend this one, which does require wiring for install. https://store.ijdmtoy.com/products/led-indicator-bulbs-20-052-switchback?variant=20448959266919

However, this information is not 100% accurate. We highly recommend checking your OEM bulb part number to ensure the correct fitting and size prior in making a purchase.

What is the color temperature of the white light in these bulbs?

These white portion of the LED bulbs are a 6000K-6500K temperature which is white with a hint of blue.

What about resistors?

If you're converting your turn signals to LED lights it is recommended to install a load resistor to prevent hyper-flashing. You may find our load resistors here: https://store.ijdmtoy.com/products/wirng-harness-adapter-aa1037
