I opened the image and then made a duplicate. The duplicate was named 'layer 0 copy'.

Go to your Channels Panel and observe individual channels to see which one is white.

For these lamps, the Red Channel works best.

Now go to IMAGE > APPLY IMAGE

Set your Layer to 'layer 0 copy'
Set your Channel to Red.
Set your Blending mode to normal.
Set your opacity to 100%.


Yellow lamps are now White lamps.

Just lowering Yellows in a Black & White adjustment layer works really well.
