Query Approved.

Ok im not from pune but mumbai and i havent changed the coil. Also i own a P200 and not the 150/180 but everything else remains the same.

I changed the bulb to the Osram Nightbreakers 55/60 and the results are very good. The only downside to not changing the coil is that there is slight lag when using the dipper. Also no doubt if the coil is changed then i would expect the intensity of the bulbs output to be better, but as it is.. the difference is noticeable and im quite pleased with the improvement.

Also there have been reports of the healamp dome getting heated up and some say blackened but i havent experienced any blackening. If i had to, i would definitely say that the dome does get hot but shouldnt be a problem. My use at night would be around an hour.

Hope it helps.

@Absoluthavoc thanks a lot for the info dude.
could you share, how much did "Osram Nightbreakers 55/60" cost you? and when did you change it?

Actually, its the RR unit that needs change and not the coil. The Avenger one will have a straight metal clamp.. (the pulsar one is L shaped).. The earlier avenger RR units had a different socket.. but now they come with a socket same as that of the Pulsar (for the newer models).. so, they are direct plug-and-play on the Pulsar. Yes, there'll be a small lag when you switch beams not all that bad with the RR unit change.. but if you keep the RR unit stock, and change the coil and the bulb to 60/55, you'll see considerable lag while switching..

I've used Philips Bluevision 60/55 with the stock reflector. I've not faced any heating problems in more than a year of use, which also includes high RPM riding all night..

BTW: I'm in Pune (if it helps).. Bajaj spares, you'll get from any Probiking service center. Just go to the spares shop inside the service station and buy it off the counter. For bulbs, head to Nanapeth. There are quite a few bulbs which are sold single as well (Philips Bluevision 60/55 is) . and no, the colour of the light is regular (not blue, .. or white for that matter)

IIRC its about 650-700/- for one bulb (actually its a pack of 2 but the OSRAM dealer that i got it from here is willing to sell it in singles) changed it about a month back

Did you get these bulbs in H4-P43b ? (with the 3 pin projection at the socket)?.. The ones that come for cars (the ones sold as a pair) don't have these 3 pins projecting out (at 120 degrees to each other) and won't fit properly in the reflector.

Also, strangely I found all paired bulbs for cars (from most manufacturers- Philips, OSRAM, GE etc) to be more expensive than bulbs from the same company sold in a single box. There was no difference in the light either. I've tried bulbs from all 3 manufacturers at different times. The single box H4-p43b bulbs by Philips, Osram and GE are around 250 bucks each (or less), while the paired box (which sometimes also has 2 pilot bulbs) have a very high price.

@HydroXidE:
couple of queries,
1. are you implying, I should change only "RR unit and 60W bulb" and no need to change the Coil/Stator plate?
kindly refer the links

I am a bit cofused.. kindly clarify.

mine if Pulsar 150/ UG3/ 3 months old.

The thread on BCMT has been a result of several discussions on the same subject since 2005 (even on XBHP), sadly the old threads here aren't available here.

I can tell you things from my end. I've changed the coil twice on my bike (first time it was the stock coil with extra winding and the second was the avenger coil), and changed the RR unit thrice as well. I've used bulbs as high as 140/100-GE, 100/90 Osram, and 60/55 Philips. My first few setup, where I had changed just the coil, and had a custom RR unit build up ran into several problems resulting in bulbs burning out. At this point I was already running the Avenger coil. My custom RR unit also succumbed to faults causing further battery problems etc, and at that time I switched to Avenger's RR unit. But, from what I've seen so far, both coils seem to generate sufficient power.

So, the best order in which to try things out is to go with this sequence.
1. Bulb, 2. RR unit and 3. Coil.

First change the bulb to a higher wattage. You'll get slightly good light at higher RPM, but bad light at idling/low rpms, and there'll be noticable delay when switching beams. Then change RR Unit. This should get you decent light all the way (at low RPMs too). I have a friend who has done just these changes (on a 180) and is very satisfied with the light (and I've seen the light too). So, based on this we can assume that the coil change won't be necessary. So, change the coil after you've done the above and still not getting desired results.

There aren't any technical documents that discuss all this in detail, so most of this are based on personal experiences of what various people have tried.

hey, which version of pulsar do you have? is it UG1?
i guess, difference in personal; experience might also be different versions' wiring and all.
i guess, P150 UG3 is quite an improvement in terms of electrical features like LED, Digi meter and all..

I sent you a mail.. I doubt there's a wiring change..

BTW .. my pulsar is in a seized state. you can borrow the Avenger RR unit from my bike for a couple of days to try things out since its the easiest thing to change (just plug and play).. also noticed your post for seat cushion.. i could help you with that too.. and I stay in Baner..

the Osram is a direct fit into the pulsar stock headlamp holder and there were no problems with it.

can any body say which is the best bulb for uni...................
i haven't noticed the current wattage.........

thanks for the offer dude.. a friend of mine is going to try it on his pulsar.. so i guess first i would wait for him to some up with results..
will call you up in some days..
