  • DIY Motorcycle Security 70dB Horn Speaker - Black (DC 12V)

    posted by cmjimenez

    I always try to have the best security on my motorcicle, and have bought better lamps and extra mirrors for it. I saw this horn and thought it can be a good purchase looking for my security.It was impossible to know how it was going to sound, so when i connect it I cross my fingers, hit the button and WOW!!! what a great sound. It's even louder than I was expecting.
    It's a great horn with a great price.
    You won't be disappointed, cheap and good!!!
  • AV752512S DC12V Brushless Cooling Fan

    posted by Arismar

    Good airflow, silent, easy to assemble, good quality. Has the small connector with 2 pins for connection universal computer Motherboards. Favors direct this airflow, focusing where else if requires.
    To facilitate its application in various other positions could be increased the size of the wire in approximately 10 cm. Screws for fixation would also be welcome.
    Is a good product and serves its purpose very well. Increase the wire size would facilitate your montage in other positions.
  • 20 Watt white ledchip of good quality.

    This type of chips is own by me in several wattages, This one, the 20 Watt version is less critical in its cooling demands as the 30, 50 and 100 Watt but still, it needs GOOD COOLING!!When that is in order, the hughe amount of pure white light -like sunlight- is produced without problems for a long, very long time.Even some more than 20 watt is no problem, just keep the chip nice cool
    These leds must be shielded , so you can"t look right into them, the 20 emmiters are long time in your vision when you look in the working led, it is awful bright.
    Best buy, ther 20 Watt version can be cooled more easy than the 50 Watt version.They are ideal fur using them in the kitchen or places where is worked with colors.You can build them in uplighters or armatures wich diffuse the light, they are to bright to look in to sodo not use the bare emitter where it ban be seen directly.Because it's lifespan you can build it in completely.When good cooled and with about 15 Watt, you propable never have to replace it!!
  • Good little switches

    Bought 6 of these to run lights on my truck,- 20A switches so will power almost anything you want them for.-comes with a built in light so I can find them at night.-work great for the price, on the shelf here in Canada there $5+
    I do alot of mods to my vehicles so will be coming back to get more.
    Great switch for anyone! easy to install in tight places too!

    Very nice small blue LED diodes.Light level is very nice, not to much and not to less.
    Cabel is long enough for easy mounting, and resistor mounted is well protected .You might put another alike product in stock with a 50 cm cable, that will be easyer to mount in some cases, for sure when used in my car.
    Over all, quite OK product, no problem with the quality.Safely delivered in sealed ESD bag :)Very professional !
