All the bulbs in the car are the same. I bought this kit and they work amazing in the cabin and also trunk. I bought morimoto license plate lights and those are bright asf too.

These are 194's theyll work in the trunk and the running light in the headlight housing and for license plate lights

These are 912/921's that i put i the reverse housing https://www.amazon.com/gp/product/B0728DYR9H/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1

oh i didnt even notice that you said Q50, these are for my g35 and g37's im sure infiniti hasnt changed the bulb size but id double check to be sure. http://www.modifiedlife.com/2014-infiniti-q50-change-light-bulb-size-guide/ This site is what i usually go by and it says there arent bulbs to change.

my best advice is to yank out the OEM bulb and look for a part size, if they do indeed match one of these auxito lights, it will defintiely make a HUGE difference.

I bought some LED lights from amazon that are really bright. Here is a link to what I bought: https://www.amazon.com/gp/product/B07RYPNW4G/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B071LHP5WP/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

I've upgraded my lowbeams and foglights twice, and just finished upgrading all the side marker and licence plate bulbs, all to LED. I'm very happy with my lights right now, especially the low-beams and fogs.

Here's the bulb chart for my 2014 Crosstrek, you'll have slightly different options for all the bulbs on your 2016 Crosstrek

Looks like you have different fog lamps than the 2014 model. If you plan to upgrade, look for deep amber yellow. They make a huge difference in the rain/snow/fog compared to white or off-white.

Lowbeams = H11 https://smile.amazon.com/gp/product/B07DGVQBVP/

Fogs = 2504 https://smile.amazon.com/gp/product/B07SBJ4SFL/

Sidemarkers = 168 https://smile.amazon.com/gp/product/B071LHP5WP/
