Halogen to HID or LED

HID bulbs also require ballasts. One on each side for each bulb.

LED bubs are often much larger around the base of the bulb due to heat sinks/cooling fins, and sometimes fans. You're going to have to make sure that you have enough room for them.

That said, I have been using 35w AC HID bulbs (4500K color temp) in our 2011 Prius hatchback for many years without problems. Also, same setup in a 2010 Toyota Camry.

I'd go with good quality LED lamps.

I've had HID's installed in my older cars; nothing but issues.- but it was mainly the ballast resistors blowing out. If you install HIDs; you'll need to double check your OEM wiring; it needs to be able to handle the additional current draw. The safest route would be to install a HID lamp harness w/60Amp relay tapped directly to your battery; of course it also needs to be fused properly. You can also avoid the ballast resistors blowing out by sourcing OEM resistors from a newer car, that came stock with HIDs. The OEM ballast resistors, hardly ever blows out. Usually about $100 each; when I looked into them several years ago. That's when I switched to LEDs; the quality and light output was almost equivalent to HIDs - and a cheaper alternative with less hassles.
I installed LEDs in my old 2012 PriusC. It was plug-n-play. You'll need to watch the polarity when hooking them up. Standard incandescent lamps don't care which side the positive or negative comes in on; but the LEDs does.

Hope this helps.

PS: HID's can melt your plastic headlamp housing. It puts out a lot of heat and a 2014 does have a plastic housing.

 

H7 standard bulbs in “bright white” frequency every time. Tried halogen - overheated and lasted 6 months before blowing.

 

I say LED as well - not some cheap crap tho - I have 2 sets of these and the light output is excellent....
