Questions & Answers

Ask a Question

Will this work on my 2020 subaru forester sport, and does it need a resistor to prevent hyper flashing?

Since your vehicle is still so new, unfortunately, we do not have any information when it comes to the type of bulbs your vehicle uses. To confirm which bulb is needed for your vehicle, please check with your OEM bulb and/or your owner's manual for the bulb type. 

We do recommend you install a resistor to prevent hyper flashing as well.

Do these come in a pack of two?

Yes, it is for 2 bulbs.
