AUXITO 7440 7443 LED Bulbs Amber Yellow 400% Brighter T20 7440A 7441 7444 7444NA W21W LED Bulb with Projector for Front Rear Signal Blinker DRL Side Marker Lights

I have a 2017 Fiat 500e (all electric car with a short range battery) and I am trying to find LED bulbs to save as much electricity as I can, also, I like the brightness.Pros:1) these are brighter than stock. Fine for front signal lights, probably fine for back signal lights.2) they run cool because they DON'T have BUILT IN LOAD RESISTOR CIRCUITRY/CANBUS decoder. LEDs DO NOT like heat so I suspect these will last longer than bulbs with built-in CANBUS decoder circuitry that run MUCH hotter.3) the power draw measured at 3.01W, compared to my stock incandescent bulbs which measured at 19.35W. One could also say that these run at 16% of the power of the stock bulbs, or, GREAT power savings!Cons:1) these DO NOT trick the CANBUS on my FIAT so they will need an additional LOAD RESISTOR or load resistor circuitry/CANBUS decoder. That is a big deal to me because I don't want to damage my factory wiring connecting a load resistor. Also, load resistors use all the power I am trying to save with LED lights.Conclusion:If you have an old car without a CANBUS system then these may be perfect for you. If you don't care about power consumption and want an LED that will run cool with an exterior load resistor, then these may be great for you. If you have a CANBUS and you don't want to modify your stock wiring, then you may want to stick with the old faithful, albeit dimmer, incandescent bulbs.STAY IN TUNE:I am performing a test of various small, high resistance, load resistors that I simply place across the leads of the bulb base to trick the CANBUS. So far I've tried 100 kilo-ohm, 50 kilo-ohm, and 1 kilo-ohm resistors across the leads and they did not work. I will be trying a 150 ohm resistor next, if that works, the total power draw will be raised by about 1W, for a total of 4W power draw, or 20% of stock power. Still a pretty good savings....

These are ludicrously bright, to the level I didn’t feel comfortable having them installed on my car. Also, they also hyper-flashed meaning that I’d probably need a ballast or load resistor to make it work. For reference my car is a 2019 toyota Corolla. It may work with your car, but be warned - these are twice as bright as halogen turn signals.

Very Bright! Leaving the “Easy to Install” at 5 Stars even though it was very difficult to get this into my headlight assembly, however my assembly is VERY small.

I needed resistors to run these properly, but they are super bright and visible from every angle.

Very bright bulb and bang for your buck, but it does not have a built in resistor so it hyper flashes. You will have to buy a separate resistor and tap it into your turn signal harness. But if you like the hyper flash look then this is for you. 👍🏽

The media could not be loaded.  Very very bright. I run all Auxito LED on my vehicles including headlights,Fog lights, Back up lights etc. They’re very bright and very reasonable price tags. Oh their interior LED’s are truly the best.Depending on your vehicle you might need a load resistor which is why my light is blinking so fast. They’re ordered and once here I will post a new video.Highly recommend.

They make my blinkers blink very fast. Annoyingly fast. I'm going to give them a week then remove them if they still annoy me. They are bright and very easy to install so I really want them to work. All of the other lights from this company worked perfectly in the same car just not the blinkers.

This is an awesome and bright turn lamp bulb except that it hyper flashes on my ‘21 Pilot.I’m not going to invest in a resistor though so ended up returning it right away.I didn’t plan on doing more than plug n play for this, so I am disappointed.
