Ajxn 10 PCS Car LED Instrument Light, T5 3030 3SMD Wedge Bulb Instrument Cluster Indicator Light, 74 37 27 17 2721 Bulb Soft Beam Canbus Error-free, Universal for Most Cars Accessories (White)

I just plugged them in and they worked great nice and bright

Bueno

I was hoping it would be brighter than stock. They’re just bluer

This set of LED cluster bulbs, T5 size, do work. That being said they are not what I would call a universal fit. They fit in a couple of the sockets in my Jeep, but did not fit in others.As noted in other reviews, swapping out incandescent bulbs with LEDs can be challenging.The polarity issue is the biggest one. A standard incandescent bulb really does not care what side is positive and which is negative.LEDs do care so you should take the time to verify polarity before putting the cluster back into service.Also on some vehicles, the dimmer circuit can mess with how these LEDs work. Again try before putting the vehicle back together.Here is how I rate items:5 Stars = Exceeds all expectations, A definite buy! (Very Rare)4 Stars = Excellent find, you should definitely give it a shot.3 Stars = It works and functions as advertised.2 Stars = A little scary, possibly OK, it may work out.1 Stars = Avoid this product, not worth the effort.

Just what was discribed just what I ordered,Happy I bought these

Said it would fit my truck. This is more of a rectangle shape and mine is more boxed shape. Bummer. Looked promising.

My 2012 Fiat 500 has 2721 bulbs behind the climate control knobs in the dash. Description says these will replace a 2721 but I was not able to get any of these to fit into the original bulb socket in the Fiat. Luckily I also ordered the regular Sylvania 2721 in case these LEDs did not fit as I have noticed many descriptions are not accurate. Using test leads I can see these are very bright but not much use to me for this application if they do not fit. I also ordered some T5 sockets online and these LEDs do not fit in those either. I'll keep these for some other hard wired project but would not try these if your replacing bulbs in a socket.

These mini Leds does fit Toyota tacoma 99Ac control system + shifter no issues however I thing just choose the warmer color for this truck
