Our car’s headlights are a mixture of LED, HID, and Incandescent lamps.

All our externior lights are incandescent, i.e. the original models, because I want to keep them legal. We also prefer the light of incandescent (sometimes I still use incandescent flashlights when runtine and weight are not an issue).
Our interior lights are leds, nothing fancy, just something more powerful.

My dad has a 2008 Toyota Tundra, and I just bought him a pair of LED headlight lamps for his birthday. Made by a company called SEALIGHT. They are awesome.

Gonna try to finish the conversion in the form of Christmas presents.

Our car (A 2019 Chrysler Pacifica) came with LED and HID headlights from the factory. We haven't retrofitted them for anything else.

My 01 Malibu has LED projectors retrofitted into the housings.  It's an integrated unit but the driver is external.  There's a threaded shaft coming out of the back of the projector and you basically split the headlight apart and put the shaft through where the bulb would go, put a nut and a gasket on the other end and then align it.  Perfect cutoff, no glare to oncoming traffic and it lights the road very well with no excessive light in the foreground.  It's really the only safe way to do an LED retrofit on a car with reflector housings.  My 2008 Audi A6 Quattro has 35 watt HID projectors, those work good and I don't plan on messing with them aside from repairing the burnt up wiring for the adaptive headlights that sweep side to side when you turn the steering wheel. My 1996 F-150 is awaiting some sort of proper modification. Looking into doing HID projector retrofits.

My daily driver (05 Malibu) just has the stock halogen setup for the headlights, they've always worked just fine for me. I've been working on replacing most of the interior stuff with LEDs though. The stock cluster and climate control lights were just small incandescent bulbs with blue silicone covers that made them a sickly greenish neutral white color. I have been replacing them with 5mm white LEDs and the improvement is huge.

Mine (99 Corolla) still has the stock H4 halogen lamps. They work fine when most of the other vehicles nearby are also using halogens but the amount of vehicles now with high power 5000K LED headlights that overpower everything makes me sometimes want to put in LED retrofits too. I'd imagine if I use proper projectors in a brand new headlight housing adapted for them I shouldn't have too many problems in terms of spill and having the correct cutoff. Besides a lot of other vehicles in my city seem to have poorly adjusted headlights so I can't imagine a properly adjusted setup having that many problems.

Most of my night driving is in the city on well lit streets so they've been ok for me so far.

Indicators (signal, brake, reverse) are all still incandescent, as are the dash lights.

You'll find that doing a threaded shaft project to retrofit on the factory headlights makes them 10 times better, much better than those stupid plug and play LED's.  I say go for it, you'll have a much more powerful high beam if the other people in your town have terrible headlights.

As far as I know, when the headlight output exceeds 2500lm, the headlight has to feature lens washer (not washer exactly, but a device keeping it clean; it uses to be just extra washer jets, activated every 2'nd activation of the window washer) and an automatic leveling system. It is a requirement for the car to be road legal, to prevent glare.


As pretty much all halogens are below 2000lm, cars designed for them use to not feature any of these. So when a car is equipped with "just halogens" from the factory, it usually does not have any of these features, nor any of the supporting components (leveling stepper motors capable to constantly moving the headlight without wearing out after a few hours, suspension level sensors, all the wiring, ECU, the tubing for the headlight lens washer, the washer pump for it,...).

When the seemingly car is sold with the HID, it has all these features build in. In fact all these featuyres required by the legislation form the majority of the cost related for that option when you order a car with HID vs halogens.

There was an attempt to get rid of the cost of these systems by going to 25W HID's (so to stay below the 2500lm), to offer "HID headlight" without the extra cost of all those systems. But this very quickly died, as LED's took over the headlights in the meantime (as a more "cool" feature), so these "polished c**p" spec cars (bragging about the "most cool tehchnology" but for cheap, so below 2500lm) very quickly switched to LED instead.

So because the only available HID kits are the 3000lm 35Wones, any retrofit using them (for low beam) becomes not road legal. Don't tell me you will be installing all the systems required for the dynamic leveling...

My Taurus has halogen headlamps but strangely in what appears to be projector beam housings. You can't see the bulbs at all. I wish sometimes I had the SHO trim level as it has HID headlamps instead (thus the projector housings). The rest of the lighting of the car is a mixture of incandescent and LED. The interior lighting is cool as it has color changing LEDs that light up various areas such as cupholders, the floors, etc at night while you drive.

My wife's car: 100% LED exterior lighting.

My car: HID headlights and the rest all LED.

My truck: HID headlights, LED tails and the rest incandescent.

and the rest incandescent.

Including turn signals?

On the truck, headlights are HID, front turns/markers are incan, fogs are halogen, tails are LED stop/turn, incan reverse and plates.

It's an old truck....

We also have incandescent blinkers on the front.
