For the 1st-gen like the @DenCon509 Pop & my '13 500e, these work FANTASTIC. As great as the amazing OEM eGolf LEDs:

"Hikari acme x" on Amazon. Just make sure to get the 2022 "Hyperstar" version, in the right model number for the car.
I would bet they'd also work great on the 2nd-gen 500e IF it also has projector headlights like the 1st-gen, not reflector headlights.

I posted about them on the 1st-gen Fiat 500 forum here:
LEDs that work without errors

& a few posts later on that thread I wrote a review, & then later on some model-specific installation tips for those exact LED bulbs.

I agree, which is why I didn't mention it until @DenCon509 brough up his 1st-gen.

However, both generations have projector headlights, right? (except any 2nd-gens with OEM LEDs) If so, I would have chosen the same bulbs, except maybe if the OEM LED bulbs fit:

I started my research "from square one", since it looked like LEDs have been getting better even since the last reports I'd seen. So I chose the ones with 4.5 stars out of 2,316 Amazon reviews for many different cars. The only imperfect reports I saw were with reflector headlights.

I'm VERY happy with my choice. I could have saved $57 by going with only 4.3 stars out of 395 reviews. However if I was then only as impressed as @DenCon509 seems to be, I'd be wondering how much better the Hikari bulbs are.

No biggie. In fact, it may have helped: It appears that projector headlights are one of the similarities, so the amazing 2022 Hikari Hyperstar LEDs might be equally amazing in either generation.

Oh! H19 looks unavailable from Hikari 🙁(the fantastic LEDs I mentioned above).

 

[Electric Tire Shredder]

I scoured Amazon for H19 & found nothing real at all, not even halogen. Maybe they're not used on any car sold in America, & since Amazon knows where I am they're filtered out.

Maybe one of you can check Amazon for Hikari & see if they offer H19 there. I bought the Hikari "HyperStar", since they had SO many GREAT reviews on many different cars with projector headlights, & they ended up working AMAZING in my 1st-gen 500e.

I've been wondering if Fiat intentionally specified the rarest bulb, so that if you want LEDs you have to buy one of the more expensive versions of the car, that come with them.

If you can find a white wall or garage door after changing only one bulb, a pic from the center of the windshield shows the pattern & brightness comparison, like this one on my 1-st gen 500e:

A pic from ahead of the car doesn't really show much:

they come with two black boxes - the first is for LED drivers I believe and the 2nd for the Canbus? I tried with just the first box and they work perfectly so a significant reduction in cabling and black boxes.

Thank you for doing that test!

Personally I don't mind multi-colored lights. I think the back of a car looks fine with white, amber (signals) & red lights, & the front with white, yellow & amber.

it would take no more than 20 minutes.

So you could switch them back for an inspection, & then put the good ones back in. 40 minutes total time. Once per year?

turn them clockwise

"Clockwise" as viewed from ahead of the car, right? (counterclockwise if you could view them from the driver's seat)
