Maybe other people will have different results, but I was extremely disappointed. I bought these bulbs to replace the fairly dim bulbs in the dash of my 1996 Ford pickup, which has 194 style bulbs.  I had already replaced my dash bulbs with the &#34;high output&#34; filament type 194 bulbs. They still weren't bright enough for me, so I decided on LED's.  These Jtech 5smd bulbs were a VERY slight improvement, but not worth the trouble. The bulbs have some SERIOUS drawbacks:First, these bulbs are POLARIZED!!  meaning, they only work in one direction in the vehicle.  Most dash lights that use 194 bulbs aren't always going to light up all the time- I wanted to replace the very dim warning lights as well-you can't just make all the warning lights come on--there's no way to tell for sure that you have installed the bulbs correctly.  There is no indicator on the bulb to denote which side is to be for positive and which side is to be for negative. I had to remove all but the illumination bulbs, which I was able to check the function of.Second, the bulbs are very flimsy and not well constructed.  The led portion is not very securely fastened to the plastic socket assembly. Additionally, the &#34;plug&#34; uses cheap ultra-thin wire as the contact, which is very easily bent out of position.  You must ensure that the wire is in exactly the right position, and if you have to bend it very far, it will break. I have very little to believe that these bulbs will last any length of time at all. One of my dash bulbs has failed in less than ONE MONTH!!!Third, and this is my fault for buying the wrong style led, not the manufacturer's fault; only the flat &#34;top&#34; portion of the LED actually does anything if you're trying to use these for a dash illumination application. These might work where there is 360 degree unobstructed area around the bulb, but even when used in a reflector in the map light of my little Toyota, the light output is scarcely more than the 194 filament bulb that it replaced. There are LED's with 4 or even 8 SMD led's that are mounted flat on the top of the plastic plug assembly--this is what you want for directional light output.Bottom line, if you're looking to purchase the least expensive LED bulb, this is it.  If you are looking for a well-constructed, bright bulb to replace your dash lights, this is NOT the bulb you are looking for. To be fair, these bulbs would work fine if you're not needing a directional output light, and where you can check that the polarity of the bulb is correct before trusting it to work.
