Apologies for the newb question, but does any of this apply to the later model bikes with the Xenon headlight and the separate high beam housing? The difference between the Xenon main and the halogen high beam are immediate and obvious (main is bluish, high is yellowish), but still, I wonder if an LED module would be an upgrade on the main light, and if there's an LED or HID upgrade for the high beam module.
Mark, it isn't a newbe question. I have learned a ton just wanting to upgrade my main beam.
Yes, it applies if you are not happy with your current lighting arrangement. Upgrade is a relative term as you are looking for something possibly different than you have. In order to know if you should change something, you have to know what you have. I have seen many Xenon bulbs colored blue so that could be where the tint you see is coming from. Beyond that, it is measured in temperature Kelvin with numbers around 6k being mostly white and higher than 6k being towards blue and lower towards yellow. The bluer you go, the less usable light you will get out of it and really high are mostly for display purposes and effect.
To make a change, you need to know what you have to make an educated decision on what to buy unless you have money to burn and just buy some of each to play with. Lumens is how much light output the device is capable of producing so you need to know what the current bulb produces and then you can choose something different. Either another Xenon bulb or make a move to HID or LED. If you found the pictures I posted up in this thread, you can see the temp difference from the original and the LED side by side. I don't have any Xenon bulbs or HID to post shots of for comparison but you can make some assumptions if you want to try something. My Phillips LED bulbs are about 6K for color and 2500 lumens, far better than the original Halogen IMO. You can also see my yellow high beam just like yours in one of those pics and I plan on changing that soon.
If you want to make a change to your current lighting, find out what you have installed so you don't buy something inferior to that and waste your money and time. Another thing i have heard folks talk about is the can buss on newer bikes and changes causing issues. Since my LT doesn't have a can buss, I don't have those issues. Someone else will have to speak to what limitations the can buss has on adding farkles and upgrades.
The upgrade factor for you would be longer main bulb life with HID or LED over a filament bulb as long as you find some combination that works both with the bike and with your vision preferences and possibly greater light output depending on what you have now and choose to install. HID are generally not recommended for high beam as they take time to warm up to full brightness and flashing is really hard on the ballast with the high start up current. LED does not have that limitation so it might be a good high output choice for a high beam which i am currently exploring.
Good luck in whatever you choose to do.
