29MM/6614/6612

Product is great. They are perfect brightness and make zero noise. It came with 6 bulbs as listed and priced very well. I own a 2002 Mazda Protege5 and even though the sizes were off by a couple of millimeters compared to the old bulb, it still fit like a charm. I also installed the bulbs in my friend’s 90s GMC Sierra and they fit pretty well. Highly recommend for people looking for “Festoon” type bulbs.

These bulbs are very good alternative for the OEM bulbs. They are very bright, which is very good at night. Good improvement from the original bulbs in my car.

Purchased and installed in my 2008 Honda Fit ceiling light housing. The OEM bulb is anemic, very anemic. I purchased another set that contained a 31mm festoon led bulb but it only doubled the light output of the original. Better but not good enough. I narrowed the choices to this set of 6 and another set that was rated at 400LM. However, it had 6500K light source -- a bit whiter than this one and it used a tad more power (2W rating). While I would have preferred to have the 400LM output, the LED's color is coolor and for me, 6000K is better than 6500K. After installing the 6000K LED lamp, the cabin lighting was much, much brighter. I am very glad I decided on going with these LEDs. Every Honda Fit owner who feels they need for more cabin lighting should consider buying this product.

Okay, it works, and the price is decent. But there is not protective tube around the chip, and the metal end caps are secured to the board by the flimsiest supports. When you insert the bulb into the holder bulb, the end caps bend in on both sides. Imagine taking a rectangular card and putting each end into a cup that just fits. Since there’s no support, the cups will easily tilt. This would be in contrast to a bulb where the LED chip was encased in a glass or plastic tube, and the end caps fastened to that tube. There is no tube—that is to say, there is no bulb, so technically, this isn’t a bulb. Also, this bulb is about 2mm shorter than the original 36mm bulb, and the end caps are slightly rounder. I’ll get a picture later. It still fits, but the vendor should at least get the dimensions exactly correct. Given that the bulb is kind of flimsy, I’m not sure how long it will last. But for now, it’s working, nice white light, not crazy bright like I feared, and definitely much brighter than the OEM.

I put these in a 2006 Lance camper skylight. The old ones were not cutting it. These are a huge upgrade. Not overpowering, crisp brightness, plus LED. I had to bend my bulb prongs to hold the bulbs so they wouldn't twist around. No biggy. I also used a small screwdriver to help lift the bulb corner in place during installation. Overall great, it's a 6pk, so I have 2 spares!

Replaced the interior light in my Toyota Solara with the Auxlight led. Bulb went in easily and had no clearance issues. The white led light looks much nicer than the yellow from the stock bulb. It is also a little brighter. My other car has the same size bulb (stock), but I replaced it with a panel that has 20 led. The 20 led is much brighter, but when I leave it on for a while, it gets so hot that I worry about my dome light cover melting or burning. This one is a lot cooler but not very bright. It’s bright enough to see (at night), but not bright enough to read. My 20 led panel is bright enough to read (and it will also fit in my Solara). So, I guess it depends on what the goal is.

Fit perfect in my 2009 Honda accord. Super bright. Well worth 8 bucks.

For a non auto mechanic, the term "festoon" bulb means nothing; I think it means a linear bulb with terminals on either side. However, there are two terminal shapes, conical/pointy, and cylindrical/flat. Disregard what almost any auto bulb matching finds (AutoX and even Amz); take out the old bulb and measure it to the nearest mm. According to Toyota, Amz and big box auto parts, the Tacoma uses a 31mm (1.25") long festoon bulb; IT DOES NOT. At most, it was 27mm long. When the terminal are clipped into clasping C-clips, there is no compressive tension along the length of the bulb, so even a mm or two length different is usually fine. However, when the housing retains the pointy tips of conical terminals with longitudinal compression, even 1 mm over 27mm leads to likely bending of the flat middle portion of the LED bulb. In that case, the only LED festoon bulb with enough solidity to resist bending is the Sylvania with the LEDs completely encased in a cylindrical housing; however, the Sylvania only comes in 31mm length, 3 or 4 mm too long for my 2002 Tacoma. The light works fine, if at no particular added brightness, even when bent in the middle. So, the takeaway is a notice to retailers, and to designers: 1. Please specify if the festoon terminal are pointy or flat; the former is usually subject to strong compressive force, whereas the latter is not since it sits in a cradle. 2. Retailers, if you don't want returns or dissatisfaction, please ensure, by actually measuring with a micrometer, the end to end length of cone-tipped festoon bulbs. 3. Toyota, please look more closely at exact bulb sizes and update all your retailers, including Tacoma dealer parts systems. The DE3022 code seems to encompass lengths from 28mm-32mm, and that is insufficiently precise for the compressive bulb holders on the Tacoma 2002, which struggles even to accept a 27mm long festoon bulb. 4. LED bulb designers, the design of placing a flat array of LEDs between two conical termini is not rigid enough for the compressive forces of the Tacoma's (and likely other makes') spring loaded holders. The points have to fit into small holds in the metal receptable ends, and the act of the compressive spring bends the flat middle part holding the LED's. Do like Sylvania and encase the LEDs within a solid cylindrical housing, arranged centrally. 5. Bulb retailers, please specify a) Lumen emitted, b) Start up delay, c) Wattage consumers, d) Kelvin light quality, e) MTBF in terms of off an on sequences, f) expected lifespan for continuous ON, g) temperature maximum. All in all, for an older model Tacoma, the LED festoon equivalent is under-engineered; it's better to stick with the traditional filament type. With such small bulbs, the energy differential is inconsequential for the consumer, and, on a societal basis, the use of non-degradable plastic and the manufacturing process is overall likely worse than the making, using and disposing of such tiny bulbs.
