Rear Bulb question

[ottawasierra]

I'm ordering LED bulbs for the tail lights on my 2015 GMC Sierra. Just wanted to confirm how many lights I need. Are their two taillight bulbs (7443) per side and two marker lights (194) per side and one reverse light (921) per side?

So I would need 4 x 7443 and 4 x 194 and 2x 921?

Do I only need resistors for the taillight bulbs that blink?

Also, for anyone who has done this, suggestions on what bulbs to buy?

 

Thanks guys

3, 921 Sylvania LED for the 3rd brake light housing. 2 for the rear cargo light and 1 for the 3rd brake light.

The reverse uses 921 as well so 2 of them obviously. License plate 2825. Now the brake light due to the blinking/ hyper flash, i do not recommend messing with them.
