Tried a warm white LED (yellower light) and a cool white LED (bluish color).
I think the yellow is better for seeing. At night, the yellow LED lit the interior better than the stock bulb.
I attempted to take some night shots but my camera phone appears really dark when the interior was actually well lit to see in person.
