Fast ship great product

bright and good . overall happy

Turns out older vehicles are set for a specific impedance and causes hyperflash, for me i was not lucky enough to find an eazy replacement for mine but the headlights were bright and just plug in play into the factory plug.

I like these lights they’re super bright just bought two packs for my truck and 3 out of 4 of them were white the other was orange and I gotta buy another pack of them bcus I got a car show this week and hope the new pack comes in other then that they’re greatUpdate new ones came in and we’re all orange and aren’t switchbacks like they advertised how you gonna give me 3 out of 4 white bulbs then when I order a replacement u send 2 orange bulbs

They work...Except my car (2010 Subaru Impreza 2.5l n/a Premium) does not recognize they are installed. Now my blinkers flash quickly as if a bulb were burned out.And only the orange light works?I am sure there is some kind of simple fix...Other than that, they are bright and seem to work well...*edit*Turns out I had a fuse blown. These are excellent bulbs. Look wonderful from the outside and function exactly as described. Turns out I still need a 6 ohm load resistor to make my vehicle recognize them, but that is mentioned in the product description.SUPER BRIGHT TWO COLOR BLINKERS!

I want to note that the only reason for the 4 star review was that the company was honest about thee hyperflash risk....and the price. While I did research resistor options, i found none worth the investment/risk...it made more economical sense to purchase another brand for me that has resistors built in....which I did. I believe that if your car is already wired for 1156 LEDs from the factory, you shouldn't have a problem...mine was not..so...take this into consideration. Overall...its a good bulb.PROS: they seem to be decently well-made. They fit very easily and they are very bright. They are indeed affordable. SO if hyperflash doesn't bother you...you'll love these bulbs. And the company had the integrity to state in the description that the buyer would beed resistors.So i will review this bulb in full and be objective and fair to them.I had been re-searching for LED headlight assembly replacements for the CRV but after installing these because they are switchbacks the light from them in white mode is so bright that it makes the old factory CRV headlight assemblies look like one solid white LED headlight and they match the LED replacement H4 bulbs I bought from a different manufacturer in fact they look extremely good and they are bright enough alone in parking mode to drive on if you had to an emergency. I’m not certain that they aren’t irritating other drivers because the beam is focused in the same area as my bright lights but nobody has flashed me yet. I will add some pictures soon but they really are a nice upgrade in tandem with a matching 6000 K quality LED headlight bulb. The bulbs are used for my headlights are the FAHRENH4/9003 and so far I am very happy with those and the colors for those lights are 6500 K but it’s unnoticeable When paired with the switchbacks. The white light from these lights are bright enough that it’s even noticeable through my LED headlights and adds to the area of coverage of forward light down road. But like I said be aware if you use these because they are bright that the housings that these lights will go into are not calibrated for bright light and you may blind other motorists but so far like I said I haven’t been flashed on the roadway or honked at I think people are getting used to these LED lightsCONS:The only reason these didn’t get five stars is because there is a delay it’s not bad and it doesn’t happen all the time and being since it’s not a primary light source that’s not an issue for me currently. Also I have hyper flash but they are bright enough so that it’s still very noticeable and though irritating because of the blinker sound I do believe that they are functional and maybe more noticeable as with older LEDs that weren’t as bright or as noticeable the hyper flash would render them useless when it comes to safety reasons. These because of the quality and brightness don’t have that issue. I’ve read reviews where other owners don’t have issues with the hyper flash but if it’s something you can’t live with you may want to keep looking and reading reviews.

Bought 2 sets and all 4 bulbs were cheap and didn’t work built in resistors can barely handle any load if your from Canada looking to add resistors to your truck don’t buy these

This product is good at first but after a couple of months it loses some LEDs and starts. To fail, it lacks quality in material duration

Bought these to replace a different set of switchback leds I bought elsewhere. I couldn’t get the other set to work in a 65 Mustang with all new wiring, but these worked perfectly. I do have electronic flashers in the car (which you will need if installing in a vintage car).Very happy with the purchase.
