LED issues with honda Insight...

    FOUR leads? I may be wrong, but don't dual filament bulbs for tail/brake lighting have THREE contacts: a hot lead for the brake filament, a hot for the taillight filament, and a common ground for both?

    As a start, why not check the number of contacts on the OEM bulbs vs the LED bulbs? And their locations on the base of the bulbs? Maybe the LED folks sent the wrong bulbs? The fact that the orientation affects the circuit strongly suggests a mismatch.

    I'm rooting for this to be figured out so I can go out and buy a set of LED's just for my tail/brake lights and front parking lights since those are on the most and would not require messing with the flasher unit!!

    I just went outside and took one of the stock bulbs out to check the leads.. Yep there are four leads on the bulb.

    I'm assuming its the correct type since it has 7443 written on the housing of the LED.

    Just for giggles I hooked up the OHM meter again and tested the stock bulb. It does NOT ground like the LED does when I touch two leads (it only does it on a certain combo of two leads... none of the others)

    That makes me think there is a issue with the LED's

    EDIT: looking further.. two of the LEDs in the LED are connected to each other and goto one side of the bulb. Makes sense, since its just a ground and the LED varries brightness from the same LED to achieve the braking brightness effect. I'm very curious now...


    I PM'd Randall who got bulbs from them as well. He isn't having any issues with his bulbs so I just need to make sure he got the same type as I did and possibly get him to hook his up to an ohm meter.

    That means they are both electrically the same. To find out if something is grounded, you can do the same with the negative terminal of the car.

    If the LED's where made in China they are probably grounding. H

    Looks like I used a different bulb for the brake than you, Blake.

    Here's the list of my choices, as installed with no problems.

    7443-15 LED Red 2 each @ 6.99USD
    7740-15 LED Amber 4 each @ 6.99USD
    3022-x9 Festoon bulb red 1 each @ 2.95USD
    WLED 6-LED White 0.95 3 each @ 3.74USD
    921-x9 wedge base LED White 1.75 2 each @ 3.70USD
    WLED 6-LED RED 3 each @ 2.79USD
    WLED 6-LED Amber 2 each @ 2.79USD
    CF13JL-02 Flasher 1 each @ 12.95USD

    There "could" also be some difference in the wiring between my early '01 and your later model, although I doubt it. And I know for sure there are differences in the Canadian models from the US models, from looking at the SM.

    Looks like you used a different brake light than I did. Hmmm... might have to order the other ones and hope they work. They won't be as bright as these are supposed to be, but at least they will actually work :)

    and since you posted which festoon bulb you used, I can finally replace that one and I'll be 100% LED :)

    I forget pretty quickly, so I don't remember exactly what my train of thought was at the time I ordered them, with the exception that I wanted to invest in power savings in prep for future EV enhancements.

    Well it could be that the ones you ordered are half the price of the ones I got! Reguardless, I'm sure they will work fine :) Just ordered them along with the festoon bulb. I'll send these high powered ones to anyone that wants to try and get them working... if you can get them to work, you can keep them as long as you tell me how you did it so I can do the same ;)

    Sean had asked about the HID kit I used.
    Spent right at 360USD.
    If some of the Insight folks are interested I could put together a thread on the subject, but it would definately be Insight specific, and specific to the kit I used, and we should get off of Blakes' LED real estate.:D

    I'm intrested in the HID's...

    I actually purchased yesterday a set of silverstar Ultra's for the insight to help brighten up the headlamps and after all the talk of HID's, I took them back this morning on the way to send the money order to Mike for my MIMA.


    Start up the thread... I'd love to see what you did :)

    Please do startup a thread for that -- I'd also love to see how you accomplished the upgrade!

    Update... The LED's for the brake lights that Randall posted do work just fine! Got the flasher in and I no longer have super fast turn signals. The festoon came in as well so now I'm 100% LED minus headlights.

    If I haven't said it before.. the honda engineer that designed the Insight headlamps needs to be shot. ;)

    I thought changing the front turn signals was bad... try changing the passenger marker lamp. If you don't have really small hands and a lot of patience, I wish you the best of luck. make sure you have lots of bandaids before you start :)

    Congratulations, Blake! That's got to be a good feeling of accomplishment! I'd like to do that to my car but I wonder how feasible that would be...

    I'm hoping either Randall or you will post a nice big write up with lots of pictures for the HID conversion. :D

    Randall is almost done with the thread. He PM'd me the other day saying he was about 1/2 way done, so I'd bet it will be showing up within the next few day. I'm looking forward to it as well.

    BUMP Re: LED issues with honda Insight...

    Sorry to resurrect this old thread, but I may be able to shed some light on the Honda LED issues. Hello. I found your thread while doing a search for LED pulsating problems. I am a Honda owner yes, hybrid no.
    While doing an LED conversion on my Element, I found the 7443's from superbright to be not that bright. I received different LEDs from v-leds. These are very bright and clear, but now I have some pulsating feedback to the instrument cluster, HVAC, and radio. This only occurs when I press the brake pedal with the parking lights off. The fact that the superbrights did not do this, and the combination of the brake switch AND the parking lights leads to the conclusion that there is some voltage leaking back to the parking light circuit through the LEDs when I press the brake pedal. I will install some small 12v relays to prevent the stray voltage from leaking back. I will post when complete.

    Welcome to CleanMPG! There are many makes and models of cars represented here. Please post anything you find out, positive or negative. I am interested in LED's and have not yet converted.

    I guess I missed this thread all together. What was the conclusion? Did it save any gas? Did Randal do his tread on the HID lights?
