I picked up a set of these during TRS's cyber Monday event to test out on my 04 STi tail lights. I have messed around with cheap LED's before and have never been impressed enough to make the switch over from a standard incandescent bulb. These however will be staying on the car.



The build quality is solid and as I tested them in various locations of the tail light, the connections made a solid contact every time. The bulbs have a nice look when mounted in the taillight housing. In the clear portions of the taillight, for my application that is the reverse and turn signal, these bulbs really stand out and improve the look of the overall housing even when they're off.



As far as lighting goes they do function as advertised. The XV-F bulb does light up the housing of my tail lights equally as bright as an incandescent. I was hoping it might be a little brighter than a normal bulb, but I am happy that it at least functions a well as a stock bulb which is more than can be said for any other LED replacement bulbs that I have tried.

I have a 2006 Scion tC, and this works great with my tail light housing. I was only expecting it to be as bright as stock, but with the design of the bulb it feels like could've been oem. Of course it is an led, so it turns instantly on/off. Great if you have a cylindrical housing.

I bought these in switchback form to see if they're brighter than my current VLED switchbacks...they are not. My VLEDS (basic ones, not the Tritons) are brighter both in running white form and turning amber form. Maybe it's just the way my turn signal housings are (04 Acura TL).



Having said that, these are pretty looking lights. The construction is definitely high quality (look a lot nicer than the VLEDs I have) and the aluminum heat sinks are machined nicely. The white is definitely 5500k (VLEDs are 5000k and these are a slightly cooler white), and the amber is a nice deep amber, not the washed out color of some cheap LEDs. I can't say how they perform compared to the first gen XB switchbacks from TRS, but these are definitely a solid choice for the price. My only complaint is that I wish they were a bit brighter!

Quality built product. Love how they look. Love the fading feature. Wish they were brighter. I switched from the Acme switch back bulbs to these. The acmes were super bright but they turned brown/bronze color on me, so I got these instead. I do like how the light is focused backwards towards the reflector. Amber color is pretty spot on. The white matches with my CBI bulbs.

Top notch craftsmanship. If anything, these are just a pretty thing to look at. High quality circuitry. The fade-in of the white led is beautiful. I had a bad connection off a relay which only supplied around 10 volts to the bulb and they didn't light up which I assume is programmed in to prevent damage. My only issue is the brightness. I can barely see the amber flasher during a sunny day. You have to know it's on before you notice it. It may just not work well with the reflector. Idk. You really only see the one forward facing led. I have some cheap amazon switchbacks in my tails for reverse/flasher function and the amber on those seems a little brighter, at least to me in broad daylight.

The base of the bulb was too fat to fit into the 7443 socket of my 2002 civic's headlights. I ended up taking a file to the bulb to shave them down a bit to fit into the socket. Aside from that little obstacle, they ended up sitting in the socket nicely and light up quite nicely. I definitely like the amber color over my former VLEDs ones, and the white did appear to be brighter than the VLEDs when I did a side-by-side comparison.
