Brightness
Customers are highly satisfied with the brightness of these LED bulbs, which is optimal and even surpasses expectations for some. They can be used effectively as passing lamps, turn signals, and daytime running lights. However, it's important to note that without installing load resistors, there may be hyperflash issues.
Switchback Function
Customers are generally positive about the switchback function of these LED bulbs. They appreciate how seamlessly the white light switches to flashing amber during turn signals or emergency mode, and some have found them to be a cost-effective replacement for more expensive switchbacks. However, a few customers have mentioned that they prefer switchbacks with a fade-in/fade-out feature instead of an instant change.

You would think changing a light bulb would be easy, but the prongs are so small that it does not lock into position.
Price
Installing the new relay should be as simple as unplugging the old one and plugging the new one in, and costs less than these bulbs do.
These are at most a $15 set of bulbs due to them not being error free.

Bought these amber lights for my truck but i sold it before they arrived.
Competitiveness
I’ve tried other switchbacks as well, and it’s hard to find a company that gets it right when it comes to switchbacks working properly!

Easy enough you connect the load resister to the black wire and the whiteblack or whitered wires outermost wires on my harness but one of the taps severed my black wire on the harness and i had to rejoin with another wire shrink wrap and retap

So note might be squeeze the tap in stages and test that the hyperblink goes away before fully pressing down
