Unsolved Creating an oscillating light behavior

I'm trying to modify the beaconSpin.lua function in BeamNG to create an oscillating (side-to-side) motion for a beacon light, instead of having it spin continuously in one direction (360 spin)

What I’ve Tried:

1. I created a new function called beaconOscillate based on the existing beaconSpin code.
2. Instead of a full 360° rotation, I attempted to limit it to -30° to 30° using math.sin() in the script.
3. I modified the JBeam props section to use this new function.

This is what it looks like. Keep in mind I am new to this, so it's not perfect.

Code:

local M = {}
M.type = "auxiliary"

local oscillationTime = 0
local beaconSpeed = 0
local electricsName = nil

local function updateGFX(dt)
  if electrics.values.lightbar > 0 then
    oscillationTime = oscillationTime + dt * beaconSpeed
    local angle = 30 * math.sin(oscillationTime) -- Should oscillate between -30° and 30°

    electrics.values[electricsName] = angle -- Apply oscillation angle
  else
    electrics.values[electricsName] = 0
    oscillationTime = 0
  end
end

local function init(jbeamData)
  beaconSpeed = jbeamData.spinSpeed or 4 -- Adjusted speed for oscillation
  electricsName = jbeamData.electricsName or "beaconOscillate"
  electrics.values[electricsName] = 1
end

M.init = init
M.updateGFX = updateGFX

return M

• Am I missing something in the electrics system to trigger movement?

• Is there a better way to achieve an oscillating motion within the existing BeamNG prop system? I would like to have a beacon lightbar that oscilates left to right rather than full spin.

Here's an example video of what I would like to accomplish:

 

seems like you changed the electrics name from beaconSpin to beaconOscillate

sirens props use beaconSpin's value for its rotation, if you change the name you would need to create custom sirens that use your beaconOscillate value... for each car that has sirens
