Good bright reverse bulbs, they were easy to install too. They are taller due to the fan on top, but they fit for me. Gotta like that white LED color too, so much better than stock bulbs.Love em!

So the features/specs/capabilities/performance of these Marsauto 7443/7440-sized LED automotive replacement bulbs receive top marks from me in every category. I hobby rather extensively and often pretty expensively (unfortunately:)), in ridiculously high quality automotive sound and lighting(custom PCB design and manufacture, custom low profile, indirect or disguised) location, layout, and installation. That being so, I've grown able to quite quickly and accurately, identify a quality LED bulb or strip for being the quality product that it is. I knew with these the minute I held one in my hand outside the packaging. There is a certain heft to these bulbs vs others when held in the hand, a marker of the higher quality aluminum alloy used to construct the housing of the bulb being slightly more dense and/or just better constructed, but the difference between these lights and competitors bulbs IS there to be noticed. A word on brightness; these are the best, brightest, front marker lights I can remember seeing or ever having on one of my vehicles. That oughta cover how I feel about the light intensity lol. Seriously, these are better than average replacement LED bulbs and I wouldn't hesitate to install them in any of my vehicles where they'll fit. A WORD OF WARNING: Do yourself a favor and carefully and accurately measure the INSTALLED space where these bulbs will be housed! I ordered these for my 2000 Gen3 4Runner. These ARE the correct, listed bulb for my vehicle BUT, this particular bulb is just under 3/8" longer/deeper than my truck's front marker light housings will allow to fit. I fabricate well and have spare time, so with some moldable ABS stock plastic sheeting I was able to secure the bulbs to the leads, install them into the housings with a tiny little spacer fabricated and now attached that allows the lights/bulbs to maintain functionality and still keep out dust and water, for now. I need to order the proper depth bulbs and make a clean install out of it, but I drive the truck on Sundays for fun, so I'm in no hurry. If it was my daily driver though I'd have been omw to the auto part store for over-priced halogens just so my front blinkers would work while I waited for the correct replacement bulbs. THAT would've been annoying lol. Hope you enjoy these, please remember to measure!

I put them on my 2006 Mazda MPV taillights. They are much brighter than original halogen bulbs. No flicker. Only one minor issue, the LED chips are on the four sides of the bulb but not on the tip. On my Mazda MPV's taillights, this is not a big issue. But in some other cases where the tip is very important, it might be.

I can only review my experience and it may be that these would work fine in another vehicle. In my 2014 GMC Sierra these hyperflash even though the description says they include a resistor that stop this from happening. So, I cannot use them.

Pretty cool light temperature but not blue, nice even light coverage and no flickering.I have pretty dark tinted windows and so my stock halogen reverse lights didn't help much, whereas these actually illuminate things behind my car to help reversing at night.They are MUCH longer than the stock 7440 bulbs I took out, so I was a bit concerned they wouldn't fit but they do with a couple mm between the end of the bulb and the inside surface of the taillight housing.No complaints, happy I can see finally.

These bulbs are an incredible improvement over the stock halogen bulbs on my motorcycle. I snagged them to increase my visibility to other drivers, and they do NOT disappoint!!!At night they throw the amber light from my turn signals well enough that I can see it reflected on the road behind me.And in the day time, they are plenty bright enough to be noticeable!

I wanted to use these on my Arcura RDX for reverse light bulb replacements or maybe even the rear break lights. These didn't fit in the sockets (7440 or 7443).I do not recommend these LED bulbs.

It's partially my fault for not reading the description well enough. The title description says switchback, but to what other color? It's definitely a white light, but that's it. Also in my 2014 Toyota Tundra, it hyper flashes on turn signals. Other than that, it fits fine, and is a good, brighter replacement for halogen bulbs.One thing to note from my installation with this LED "bulb". The LED array on the bulb is circular and mounted around a cylinder circuit board. It lacks LEDs facing out on the end so they rely mostly on a surround type of reflector in your vehicle. I had brighter (directional) output in my front turn signals than I did with them in the reverse light housings. If you are using it for a reverse light it's not as bright as those with LED chips mounted on the ends with a glass projector lens.I would give these bulbs a higher rating because they are definitely bright, but the description claims that they are "switchback" and they are not. I also knocked off a star since they did not prevent rapid (hyper) flashing on my truck. Toyota is a very common vehicle manufacturer so I would've expected them to be in their claimed "effectively prevents 95% of hyper flash", but they are not.I hope this information has been helpful to someone 🙂
