Well, errr ... you know ... actually ... errrmm ... I like it!Number 2. Oh dear.
Hell yeah. These are on my list too.I have them and they look great
Just use 3000K LED lamps, hey presto!Number 1. I'd use it in all except the visors.
I put them in and took them back out, in mine they were too bright and clinical, felt like I was in a fish tank. Standard bulbs are nice.

There’s a thing about red, it (and blue) are perceived to be the least bright for any given actual optical emission power. So the fact that you find the red brake lamps to be so bright is interesting...
Human eye (or rather brain) cannot detect that, surely?It's not the brightness, it's the fact they flash at something like 100hz.
Not just me then!LED rear lights (the red side lights) on cars drive me nuts at night.
You don't suffer from meniere's by chance John, strobing of led lights can be a small sign
Even my HID headlights flash, it's noticeable in cats eyes, Never knew HID flashed, I thought it was a continuous arc?
Just found this...

Can you actually see lights flicker?
It depends on the frequency of the flicker. People can see lights flashing on and off up to about 50 flashes per second (50 Hz) - they are most sensitive to time-varying illumination in the 10-25 Hz range. The actual critical flicker frequency increases as the light intensity increases up to a maximum value, after which it starts to decrease. When a light is flickering at a frequency greater than 50 or so Hertz, most people can no longer distinguish between the individual flickers. At this frequency - the critical flicker frequency or flicker fusion threshold - the flashes appear to fuse into a steady, continuous source of light. This happens because the response to the light stimulus lasts longer than the flash itself.
Most people cannot notice the flicker in fluorescent lights that have a flicker rate of 120 cycles per second (or 120 Hz). Flicker with LED lights may be more noticeable due to the fact that LED lights flicker between less than 10% and 100%, where as fluorescent lights dim to about 35% and back to 100%).
The light flicker may be detected by its stroboscopic effect. When objects move or rotate rapidly, they may be lit at or about the same position during each cycle or rotation. This makes objects look as if they are moving more slowly than their actual speeds - they may even appear stationary if the object is moving at the same rate as the flicker frequency (or a multiple of it). This fact is the principle behind a strobe light but it is not the desired effect in general lighting. In fact, it could be a safety hazard if someone mistakenly thought that some equipment was stationary or was moving slowly.
