  • Upgrading Electricals in Honda Activa

    Hello! I own a 2011 Hond activa. I have a few questions that I would like you to help me with.
    1) Is it advice able to use a 100/90 head lamp in place of stock,as i feel it is inadequate.
    2) Will a 5ah battery be adequate to support a 100/90 head lamp in direct dc mode over a relay.
    3) Will the 5ah battery charge over the stock coil settings.
    4) Is it possible to convert the turn signals,brake light,park signal to led bulbs. Please state the type of stock bulbs used and if possible give info on suitable led replacement.

      Re: Upgrading Electricals in Honda Activa

      I know its an old thread but I have same query too. I have TVS Jupiter which is the same class as Activa (Admin, may be we can update the title to include all scooters).

      I thought of a number of options.

      1. LED headlight.

      These only consume about 10W/15W Low/High as opposed to the 35W/35W stock halogens. However not sure whether the LED illumination points are at exactly the same positions as the Low/High beam filaments of halogens else projectors are required. Also they need DC power and involves wiring modification to DC. No extra load on batteries though.


      2. HID bulb in projector housing.

      This also involves wiring change to DC and also cutting/splicing the lamp housing to fit the projector inside. Online search indicates inconclusive battery drain issues.


      3. 55W/60W H4 car bulb.

      This would need an additional 20W/25W of power while the scooter's headlamp has only 35W to use. I don't know if the electricals can take an additional 25W or they are built with no margins at all to cut costs. An idea to overcome this is to save some watts by switching some of the other always-on lamps to LEDs.

      For Jupiter they are:
      a. Two 3W pilot lamps = 6W.
      b. Rear number plate lamp = unknown watts, someone please comment, (3W?)
      c. Instrument panel: minimum 7 lights
      1. Two (green-Economy/orange-Power) unknown watts, someone please comment. (3W each?)
      2. Four dedicated lights for Left turn, right turn, low fuel and high beam. Unknown watts, someone please comment. (3W each?)
      3. Speedometer / fuel indicator. Are these two separate or same light?. Again wattage unknown, someone please comment. (3W?)

      This could be somewhat different for different vehicles. For example, I know Activa doesn't have pilot lamps.

      However after saving all these and replacing the 35W bulb with 60W, could the wire and the headlight housing still take the load even though wattage is taken care of? Would they burn out due to the extra heat?

      Regards,
      Uday

        Hi this is an old post but still answering it as i just saw .
        1)No it will not glow fully reult will be bad than stock bulb & may be it will burn Headlight Reflector .
        2)Yes you can power it with battery directly but it will empty it faster . Than the charging it is getting .
        3)Activa comes with 5 ah battery so it will be charged .
        4)Yes you can but for turn signal you need to change flasher accordingly.

        In a simple word \"Done that\"

        1) You just need to find correct working led bulb , they are available in market along with some which are useless . They need DC supply . No 10w/15w i seen . Mine 15w/18w spread good & you can adjust the reflector accordingly .

        2) Forget it as it will drain battery & you will be out of light once battery emptied & also kick starting activa or other moped in not good idea .

        3) Good idea but will not glow to full extent on AC , while on DC it will eat battery .

        You can change all bulb\'s to led one , for parking / meter t10 bulbs on ebay you can get around 10 pc for 250/300 rupees while in market pair would cost around 50/70 rupees , depending on your power of bargaining . For brake light mine led yet not arrived so can\'t comment .

        Using this led setup on activa from around 1 month no battery issue yet , but also not much drive in night hardly 15/20 km within city at low rpm .

        Check attached picture & for comparison of HID & LED see the pic attached here http://www.xbhp.com/talkies/universa...ml#post1124809

          Re: Upgrading Electricals in Honda Activa

          The Reason I never talked about HID is bcoz I tried it as early as I got my ride. Battery died the first night. The stock battery was 3AH. Now I have a 50/55 Philips blue vision ultra, which gives a near white beam. It runs on DC over relay. Battery replaced to 5AH. I found a couple of LED bulbs for dash, an signals on ebay, but I was not sure of compatibility. Neither could my friendly neighborhood electrician confirm it. So I dropped the plan.

          I like the LED headlamp. Can you give me the product links for the ones you use, Above_All

            Nice.. did you buy the bulb online? How did you get the setup done, the DC line etc? Also can you post a photo of the low beam as well?
            [MENTION=28461]Anupam[/MENTION], I figured out the dash and pilot lamp bulbs they are T10 bulbs, available in any auto spares shop. I got 7 of them replaced to LEDs (5 dash + 2 pilot). Ordered couple of more LEDs off ebay - more powerful 3W T10 bulbs for pilots and a BA9S T4W for rear numberplate. I got the names of these bulbs from asking around in auto spares shops in Pudupet in Chennai.

              As UdayKhan mentioned its T10 for pilot bulbs. I have bought that LED headlight Offilne.

              Directly fed Supply from battery to headlight switch. So far no issue.
