    Default DIY L.E.D. Rear Turn Signals

    I was pretty nervous about doing this because i didn't want to ruin the bezel around the taillight, but a buddy talked me into it. I'm glad he did because it turned out great and I'm very happy with it.

    The first thing I did was remove the bezel around the taillight. I took it inside and sat in on my dining room table and looked at it while I drank a beer. You always have to evaluate the situation. Beer helps.

    I got these L.E.D.s from the buddy that convinced me to do this. They are 3mm dia. He got them off of sleezbay, but our local electronics store keeps them also. The chart I've got sys that 3mm is .1181. Since they are slightly bell shaped, I used an 1/8" /.125 drill bit. I decided that 5 of them would fit, spaced 1cm apart.

    The longer post/wire on the L.E.D. is the positive side, so i pushed them in the holes with the longer ones all on the same side. I then hot glued the piss out of them to hold them in place.

    Next, I bent over all of the posts in the same direction and soldered them in parellel circuit. I then soldered a resister on at the end of the positive side. I don't know the particulars of the resister. I put it there because my buddy told me I had to. Somebody more familiar should be able to tell by the color and stripes. ( I think )

    I soldered my positive and negative wires on to the single posts that were left at the end of circuit. Shrink wraped the ends.

    More hot glue.

    Now all thats left is putting the bezel back on and wiring each side to the factory wires. I just used simple spade connectors. Since they are L.E.D.s, they have to pos. to pos. and neg. to neg.

    I haven't put in a different flasher, so they do flash fairly quickly. I'm going to live with it for a while.

    Cool. Surely not legal tho?

    The size of the resistor depends on the type & number of leds and the current applied (14.5v). There are on-line calculators to work this stuff out.

    Probably not legal but I've never been pulled over once in the 4 years I've been running the ones I made myself. They're slightly dimmer and harder to see than these too. These ones look awesome.

    Thanks for the complements, guys. I'm not too worried about them being legal. Where I live, in small town Kansas, its not a big deal. Just as long as you make an effort.

    http://www.ehow.com/list_7356561_fed...n-signals.html , alright I guess it needs a reflector, and sizing issues. I do like what you did though.

    Not sure about other states or countries, but in MA, USA, they require the turn signals to be a minimum distance of 9" apart from center to center in the rear and 16" in the front.

    The fronts also have to be facing forward. This is why in MA, flushmounts are illegal, even though with most fairing mounts, they're over 16" apart.

    I'm positive they aren't legal, but when you compare it to the harley wing-nuts that run around with there chopped up oil drippers, or kids that hit the streets with there stripped down "stunt bikes", its more than enough to please the cops.

    Im thinking down the side on the rear.... and a few flush mounted on the side.
    Im in Texas so the cops are not too bad, plus my plates help.

    alright, I have no problem with getting inspection stickers in MA with my flushmounts hopefully I don't have any problems in the future, but I like the info you put forth here (love the specifics)
