I bought the Nsidius kit and changed out their halogen bulb with an led one, because the 2017 models have LED tail lights and the 4th brake light came on a half second late.
I'm not entirely sure if it's the same socket size as the ijdm, but this is the one I bought. A red bulb isn't necessary since the reflector housing is already red, so I got white, but I believe they have a red version:

Just make sure whatever bulb you get, it has dual function for parking light and brake light.
