Looking to take out the regular high beam bulbs and switch them out to HID bulbs on my ST3. Does anyone run a specific bulb or preference over the "Autozone" HID bulbs?
Thanks,
Fixter

You already have HIDs .

Lows are HIDs, highs are halogens.

That's odd. I have a ST3 and it's HID for low and high. It uses a shutter to block the light output.

Maybe it depends on year. I have a 13 ST3.

The OP is confusing anyways, title says LED and then says HID in thread text. Separate HID high beams are generally not great because they have a few second warm up time-- I guess as long as the low beams stay on, not a big deal. On the LED front, I've yet to find a good one that works in reflector housings. Also the fancy ones have fans or heatsinks on the back and you may run into clearance issues.

Every gen of ST3 had HID only for low and high... The halogen bulb you see is for the turning light.

Sorry for the confusion, when i put on my high beams they are regular bulbs ("Yellow light") that are to the left for the actual HID low beams. I will try to add pictures, Im driving a 2013 ST3. I see the turning lights as well but they are the same color as the high beams when i switch them on.

The 2013 and 2014s had H7 halogen high beams. HID wouldn't be a good idea because of warm up time and constant on and off.

I would do Sylvania zXe H7 bulbs.

That is incorrect. The 2013-2014 ST3 has a halogen high beam in addition to the main HID (which is both high and low).

The red arrow is the H7 high beam bulb, the yellow arrow is the PY21W cornering/turning bulb:

2014 ST3 here and it's bi-xenon. The "high beam" halogens are only used when the lights are off and you go to 'flash" your lights, as far as I can tell.

On my 2013 ST3, when the headlights are on, BOTH the halogen bulb and HID shutter activate. So there are 4 high beam bulbs (2 halogen, 2 HID) shining. I really love that it does that. I'm not sure if they changed it for the 2014.

My '14 ST3 has HID shuttered lows and full-beam highs, plus the halogen highs. The high beam lighting is... quite good.

My 16 has just the Bi-Xenons. You can hear the reflector clunk on and off, up/down. No other lights in the assembly except the turn signal and turning lamps. Well and the LED's.

i double checked... my 14 st3 is bi xenon hid and the halogen bulbs come on with high beams. not sure what i was smoking before. edited previous posts to not spread misinformation.

This is how my 2003 MB C230K Coupe was. I love it, so much better light. My 2016 ST has just the Bi-Xenons with no secondary lamp. Not as good, I mean it works and I can see but in snow the Xenon lights are just too damn white. The Halogen bulb was nice.
