Just bought a 2015 s plus and changed all bulbs to led. JDM ASTAR sx chipset for the signals were brightest. Look for them on Amazon. Also used their 921 reverse bulbs. Diodedynamics has a brighter bulb but not worth $90 cost for the pair imo. Next, I liked jlcconcept rear 50watt Cree brake/tail 7443. Very bright and awesome cherry red color (red LEDs). Not cheap $60 a pair. Used them on my mr2 and dodge truck. They are well made and reliable over 18 months old. All the 194s tag trunk markers map were sylvania osram from local parts store. Dome 3175 JDM ASTAR extremely bright variant. Hi beam and fog were JDM astar 6th gen 2800 lumen. I absolutely love the fog light illumination improvement. Hi beam was better than halogen oem but not a wow factor. Also had to add a resistor across each of 4 turn signal sockets to stop the hyper flash. This is the 4th car I've done led conversion to so I am rather familiar. Luckily this 2015 doesn't have ck turn signal sockets like my 2004 Corolla has. That is another topic... If you are new to doing led, there are a lot of choices,and variances in color and intensity. Fwiw, I've had to buy and return stuff, and modify to get exactly what I wanted.
