White and Yellow lenses in the same light bar

What is the benefit of having white and yellow lenses in the same light bar? Case in point is the Baja Designs S8 or the ONX6+. In a 30" bar you can have 1 or 2 amber lenses and 1 or 2 of the with lenses in each bar. What is the point? Does the one amber lense bring the overall color of the light bar down closer to the amber color to improve bad weather/dust performance?

I see this on 30" and 42" Diode Dynamics bars as well. I am just wondering why? And is there any actual benefit to doing it this way?

 

Amber light cuts through fog and sand better than white light. It can also help others identify that they're seeing the front of a vehicle, as opposed to the back of a vehicle where one would expect to see red.

 

I have a diode dynamics and rewired it so the two outside sections which are SAE driving amber are controlled separately from the three inside sections. Which are white flood. So for driving in bad weather, I switch on the Amber's. If I need work light at night (while off the road) I can switch on the white

 

How did you do that? I would like to try that with a BD ONX6 lightbar bar

 

I can't speak to the ONX6 but the DD light bar is just 6" sections that are wired together. Once the lenses are removed, you can see how the individual boards are wired together.

I got a 3/14 stranded wire cable and replaced the 2 conductor wire that came with the light bar with this. All the grounds are connected together then there are two separate power wires controlled by separate switches to connect the amber and white lights separately. There are 4/14 wires available too but I didn't think I needed to separate the grounds.

 

But do clear lenses and amber lenses on the same bar help with driving in foul weather? (i.e. rain, snow, dust, etc…)

Or does the light output through the clear lenses cancel out the benefits of the light coming through the amber lenses?

 

I don't know why any bar would have them wired to both illuminate simultaneously. All of the dual color bars I've seen (cheap chinesium) were wired for a dual switch. Run white for high visibility, run amber for cutting through particulate/fog/high contrast. You turn on whichever section of the bar you need.

Running both at the same time defeats the purpose.

 

I guess that makes sense. Yet people run their amber lights with their factory headlights on as well. How does that factor in?
(Sorry if I’m asking too many questions. Just want to learn more about this…)

 

I run low beams and down-cast ambers in the fog, and it does fine. Any "spot" beam or one that doesn't have a well defined cutoff (like a high beam or off road light) is the light that does more harm than good. Those lights tend to hit and reflect back on the suspended particles within your line of sight, causing a scatter/blinding effect. They light up the fog instead of the ground.

You basically want lights pointed like this. Ambers help because we perceive a higher contrast in that color, which helps cut through that particle scatter effect.
