I used these which claimed to be "no resistor required" & "plug & play" and they've worked perfectly since day one. No issues whatsoever and great results.

Glad I found this ... going to try something similar. I can't believe they made the rear so nice with the LED and threw a regular bulb up front. Even the ES has a nice LED strip but oh well.
I LED converted my Tundra so I'm glad stuff like this exists

 

 

in the rear yes but the front is a normal bulb unless the AWD different? Mine is a RWD and has a regular bulb up front

 

There are two headlight options on the 4GS. The base headlights "Standard Bi-LED" which have incandescent turn signal bulbs & then there are the upgraded headlights (more commonly equipped on AWD models for whatever reason) which are the "Premium Triple Beams" and these are full-LED, like the rear. They're so much better looking than the standard headlights. These are the same headlights that all GS F models have.

 

 

JDMs are not available in Europe Pictures in the link show resistors, but that might be just a generic listing.

Anybody tried a regular WY21W (7440) led bulb?

 

 

It will hyperflash without a resistor due to the lower pull of the LED. You can buy any LED bulb for the turn signals 7440 that fit and then add a resister. I believe both US Based companies iJDMToy and VLEDS ship their products internationally.

VLEDs sells some quality stuff as well:

Curious that the bulb says 7440 but don't the GS use 7444 bulbs for the front turn signals? Or is it interchangeable?

 

Not interchangeable...
7443 = Front (typically used up front since its dual filament allowing that little yellow constant marker/parking light AND a turn signal blinker)
7440 = Rear (typically single filament for just your turn single blinker)

The original poster was looking for front bulbs (7443) for his '16 GS..

 

 

 

I threw these in and they worked without any issues ... no resistors needed.
