    Got my Cheapie LED(39)s from China...-gctid371868

    Only purchased them about 10 days ago and they already arrived. Tried them on the car battery and they are extremely bright. The plan is to stick them on the underside of the engine hatch all around (4, one each side)... They have sticky glue on the back side AND are completely waterproof... Anyway, for the price (~$13 for four strips including shipping), I think they are amazing... I bought the white ones but they come in blue too...

    OK, everybody read carefully, I believe the reason the light strips were cheap is because some of them have the positive and negative wires reversed. IE. Half my LED's worked and I know I had them hooked up correctly so I pulled two sets off that did not light up and reversed the polarity of the wires and now all four light up. These LED's will only work one way. It matters which is positive and which is negative. If you hook them up backwards, they won't light... but they also won't be killed either so no problem...

    So, please check the polarity of the black and red wires coming from the LED strip. Some are reversed but are easily corrected...

    Just installed mine and they are on a switch in the engine bay. See photos below... I powered them off a bus that stays powered up when the MBSS is off.

    One more point... the LED backside 3M adhesive does not stick well to the underside of the hatch even though I cleaned them up and scrubbed with some rubbing alcohol. So, I sprayed the back side of the strips with 3M 77 super adhesive and the underside where the lights were installed. In addition, I sprayed at other locations under the hatch edge and ended up taping into the adhesive the wire runs. Worked out quite well and I avoided getting underneath and drilling holes from below up through the deck.

    Having lights in the engine bay is great as you can see.

    Is the backing on those rigid or flexible?

      They are flexible seems coated in a clear acrylic that is flexible and waterproof... You could easily wrap them in a circle or barber pole style up a pole as well.

          Got mine in yesterday. Made the mistake (wife too) of looking directly at the lights when I powered them up from a 12 v source. THEY ARE BRIGHT!! For the next five minutes, every time I blinked my eyes, I saw the LED grid.

          Awesome lights for the price.

                  Saw those and these from China actually look to be a better product... But for $13 for four of them including shipping??? can't go wrong. As I stated, if I get a season out of them, I'll be happy. and I can replace them easy enough as well...

                    good to know they might be better

                    they are 4 for the price of one of the HF units and the way you have them mounted you won't notice 3-4 leds being out I will give em a try ,, I use them in my tool box now

                        being a single 5 meter strip did you cut the strip into 4 different pieces and then wire them separately can you give a picture of the connections.very cool look

                            Doug, you beat me too it! I had already planned and researched this project for my boat engine hatch as well as my storage locker on the swim platform. Good job and now I have a heads up for the lack of stickiness.

                            Thanks
