    Hi guy's so over the weekend i installed a quickshifter (translogic) to the bike. My left hand light on normal beam doesn't work. Switching to high beam it comes on and also the daytime lights are unaffected. Previous bikes have all been sports so i'm not used to having to lights running at once without it being high beam. Any thoughts would be appreciated Cheers

    That’s what I thought but isn’t it the same bulb as the high beam? I’m going to switch the bulbs around when I’m home and see if that changes anything

    Sounds like youve disturbed some of the wiring when you did the mods, I would goback over everything you touched / moved and recheck all the connections.

    It usually turns out to be something with the last thing you worked on ......

    This may be a silly question but is the leftt headlight only main beam and the other dipped, or are the both dual lamps?

    Only asking because my Daytona had only the right headlight as dipped beam and left as main

    I was just thinking fuse or bulb.

    Most twin headlamp bikes only have one lamp lit on low beam, hi beam was the same, but it wasn't hard to make it dual lamps hi and low, just put the extra relay's in !

    It’s the bulb, taken them out and switched them over for the same result on the bulb. There’s 2 springs in the bulb which explains the high beam to low beam. That’s new to me which Is why I was querying it

    Yes, they are H4 bulbs with two filaments, one for dip and one for main. I'd get a couple of new brighter ones if I were you, Philips Racing Vision +150% or similar

    I’ll have a look at them thank you

    Seriously don’t, just use the H4’s so you can be seen by other road users rather than dazzling them so they can’t see anything!!

    Agree, and haven’t stronger bulbs contributed to issues with the headlamp lens overheating and going cloudy?

    The Philips bulbs I mentioned are H4 with the same wattage as standard. The only difference is that they produce more light and whiter light in the same area as the standard H4 bulbs, making you more visible and illuminating the same area of road more clearly.

    The problem with the production of more light is that they produce more heat ( nothing is free ) which means they run hotter part of the reason for the shorter lifespan. You will find faster deterioration of the headlamp lense ( plastic ) and also the silvering either discolours badly or burns off altogether.

    Price up a set of headlamps against the small gains for the "higher output" bulbs, I think you may find the cost of new headlamp assemblies a bit off putting.

    I would stick with std and do your night time riding withing those limitations.

    Same wattage means same amount of heat produced. You don't get heat for free.

    But you obviously get more light for free ???????

    Due to the larger amount of light produced there is more heat generated its all down to the element make up, enclosing envelope and gas fill which runs hotter for the same power consumption.

    Same energy input, more light energy produced and therefore less heat energy produced, it's simple physics. You can't create energy from nowhere, otherwise the perpetual motion machine would be a fact rather than a fiction.

    Explain how the same energy input generates more light then ? + 150% ?

    Like I said, less heat. I give up. You win.

    The higher light output is generated by running the element hotter ...... by using a different filament make up run in a different gas to facilitate a reduction in the different element "burnout ".

    Different elements have different characteristics for the same power input why use Halogen as the gas in one lamp and xenon in another ?

    If the components used were identical yes there is a correlation ......... once you change any one or more of the factors then you change the whole dynamic of the system and therefore the results.

    Tell you what, they don't generate more, which was your original reason for not buying them!
