  • [Help]: Bajaj Avenger Headlight Queries (and Mods too.)

    Hi PPL,

    This is my First post here and i'm with same old headlight query to start with. (I hope moderator will not remove this post).

    Well, by profession i'm IT manager and personally an electronics hobbyist. I own an avenger 180 since almost 3.75 yrs. Recently the headlight glass was fell off itself and broken into pieces. Also the reflector was corroded almost 30%. So it was time to look for new headlight. I visited CST road Kurla and purchased new headlight which looks like honda VTX one. I'll post my bike's pics soon. Now, the quality of that headlight is different issue. It had an old style 35/35W Bulb. I removed the Bulb holder and after some efforts using drill machine and grinding stone succeeded to fit old stock H4 Bulb.

    While the light seems enough for city driving, i'm planning to visit my native place (malvan) next month, and need some more power in headlights.

    I checked the on-load voltage and it seems to be 8.5VAC, and it's a culprit why the headlights not functioning upto 100%. Battery shows theoretically correct voltage of 14.2VDC while bike is in off condition.

    My query to you people.. what are no-load and on-load voltages of your headlights. Also i'm thinking to introduce relay for headlight, as i observe the upper/ dipper switch gets warm after 1hr of usage.

    Now referring to mods, I've just started converting the bike to LEDs, but it will take some time. I've converted the tail light with warm white superflux 43LED array, which is as bright as 30W halogen bulb and consumes 10W in full brightness. I've also purchased four 1W Leds which will be used for sturn signals. Now, i'm designing a driver for these powerful LEDs, which is likely to take 2 months more [i'm somewhat lazy ]

    Following is a tail light diagram.

    +12V R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 1 ohms R = 150 ohms

    Alongwith this i'm also aiming to convert the auxiliary lights into LED ones, with powerful SSCP7 Leds. Here is what they provide at 3.7V / 2.7Amp, a 900Lumen light. Luckily i found a only Indian distributor at Thane and each 10W SSCP7 Led costs between 500-600Rs. Still to buy one as he didn't have 900Lumen ones..

    So, Friends Let me know about no-load and on-load Headlight voltages, whether headlight relay works and also about your LED lights efforts..


    Thanks,
    Shashank,

      regarding your headlight...
      is it a dc or ac? i think all eliminater models were dc and avy ones are ac.
      anyway it seems from the voltage ur batt is pretty weak,on load it should not drop below 12 volts,mine modded p 180 which is 5 yrs old ,stock battery still maintains 12.8 volts with load with 55/60 bulb!
      first clearup few quaries then gurus will be able to help u on this

      1.is ur bike dc?
      2.what rating is the bulb?
      3.is there a cutout for headlight
      4.the battery is stock?

        i thought avi 180 have 55W bulb.. thats why we P150 owner switch to Avi 180 stator plate to fix the 55W bulb .. check out with your manual..

        no idea about circuit though..

          AFAIK relays work only if your headlight is on DC.


          Can anyone tell me diameter between outer edges of Avenger headlight ?? I was thinking of putting them on my Unicorn

            Your h/l works on AC, and has no relation with batt voltage - its a separate ckt. Voltage on DC part (batt) should be above 12.8V with engine ON. AC part (h/l) should be 13V or so.
            Your biking tells a lot about the person you are!
