I've been developing a few lights you may be interested in.... Here's an example:

Pretty obvious which is which... Headlight left, spotlight  right...

The Headlight is represented with/by geometry mimicking a headlight with a bucket(Chrome) surrounded by an enclosure(mat black), and a lens (glass material with reflective and refractive caustics) of course  caustics need to be enabled  in render settings( adds about 2/10ths of a second to render time). The Headlight has a simple default point light enclosed in it set to 100% inverse square falloff the spotlight is bone stock(also set to 100% inverse square). 

Here's an example of the lights in use, Headlights on the truck(2) set to 100% and 6 Spotlights( 2 white, 2 blue, and 2 red) on the cop-car each set to 1000% just to get them to show up.... Yeah I know the manual says setting lights above 100% has no effect, but the manual is 100% WRONG...LOL...Another downside of using Poser Spotlights is that I had to turn the  sky off because the strobe lights traced red&blue  paths across it when animating. I tried setting distance falloff but found no joy...

Image is a wip preview(10samples), in early stages. Just a test, those headlights on the truck are way too bright, at 100%X2 brightness they out-shine the spotlights 1000%X6 brightness by probably about 100/fold..... I need that sky in my animation, its what inspired me to explore other options. Spotlights ain't working for me. Another advantage is the ease of placing the Headlights where you want them, and they are always visible and self illuminating, just place 'em and forget 'em... on the cop car I had to  a devil of a time just placing the lights, and had to create "glow in the dark'  materials  to make them visible behind the Spotlights.

What do you think?  Lets get real... Thinking a couple of the 'Poser Gurus' with their advanced knowledge could do some wonderful things with this... I'd be happy to provide the Spotlight scene.pzz (first image above) for further development if they're interested.

When I have time I'll present an argument for the ease of use of Poser cameras represented by 'Physical Cameras on Tripods' (geometry)  as parent, vs default cameras represented by...well... nothing....

sending a light through a lens or having it surrounded by a reflector is a recipe for noise. Huge amounts of noise. I've tried it. I think these techniques would be great if we were working in Filmic color space and had a wider dynamic range but until that happens I stay away from that. I'm hearing rumors of an updated Cycles X or such for P13 so I'm holding out. I do have something similar in my store. A light set that parents to the camera like a photo flash.

I agree with ghostship2, using any type of lens in front of a light source will create noise although having some atmospheric hazing is becoming a trend where realism is concerned.  You should try blackbody lighting if you are rendering in Superfly; maybe attaching a wavelength node to the light source would give you better results although it is limited in its color range.  These are just options available than simply tinting the color chip on the node.

When was the last time you guys rendered anything other than 'cheap pinup art' that took hours/days to setup and render a single so-so image? Maybe I wasn't clear about what I'm doing, I'm animating car Headlights in a 'night' scene(why else would you need Headlights). The cop car scene above is a draft render(took all of 10.2 seconds, (I wouldn't say its overly noisy) final renders are 4K still not much than a min. then downsized to 1K or 720.. When frames are whizzing by at 30fps noise isn't that much of an issue.

??? Was just giving you some constructive criticism and you reply with a personal attack? Not cool.

@ghostship2: These broken shoulders in your image are really hard to look at (constructive criticism only, nothing personal)

@ghostship2: Anisotropic is totally overdone with the hair in your image (constructive criticism only, nothing personal)

troll is on ignore.

Whoa Nelly, lets not let this go off the rails....

The term 'cheap pinup art' wasn't coined by me, it refers to images of pretty girls rendered over a picture, or no background at all... 'Cheap' refers to investing little or nothing in your scene other than attention to materials and fidgeting with lighting(which isn't 'nothing', but its pretty close.)...'so-so' is as good as it gets citing shortcomings of previous term, no matter what you do there's going to be no real illusion of depth to your image . Its common terminology not meant to be derogatory. I guess whats common in one venue may not be recognized in others...

I could easily throw in other terms that would be apropos to what is common here without pointing at anyone specifically, but the group as a whole  (full of oneself // drowning in ones self-importance // strutting around like a peacock in full bloom shouting 'look at me, look at me, I'm all that and you're not' // cannibalizing-hijacking threads to sell product // anyone ever heard of the term 'brown nose'?) but, I wont go there.... Wouldn't want to bruise anyone's ego in the guise of 'constructive criticism'...LOL

Back in the day this forum was about people with common interests gathering to share tips and tricks to make better art... free stuff galore... It wasn't about any individual or cabal of 'special people'..... Those days are long gone, everybody's trying to out-sell everyone else ...

  I'm pushing 70 and it never ceases to surprise me how quickly fine outstanding people, given some semblance of authority become tyrants (giving side-eye at some of the Mods).

you try to "explain" yourself in a different way while at the same time making the same attacks.   You might want to re-read what you wrote and figure it out (unless you were consciously trying to be viscous).

I'm not an authority around here, just another Poser user like you trying to give some advice. If you don't like the advice you can overlook it instead of making an ass of yourself.

The other guy I have on ignore because all he does is troll people around here.
