Want new dash lights ,LED?? & more

Nope. The problem is basic: bulb-type lamps must use bulbs, because any other light source will not work correctly in them. It's like putting on somebody else's eyeglasses: no matter how good they look on your face, no matter how much you clean 'em and shine 'em, they're made for someone else's eyes and so you won't see properly. The same goes with putting the wrong kind of light source in a lamp designed to produce a particular light distribution (which is every exterior light on a car). Whether it's putting an "HID kit" in a halogen headlamp (see ) or putting "LED conversions" or "LED bulbs" in a brake light, turn signal, or marker light meant for a bulb, it just does not work safely or effectively.

To give a specific answer to your question about chrome: No. First off, most brake lights and turn signals made before the advent of window-clear lenses with jeweled reflectors don't have a specular (mirror-like) reflector. They have a diffuse (matte) reflector, like the "dull" side of aluminum foil. That's important; it helps spread the light evenly throughout the angles required to guarantee other drivers can see the signal properly no matter where they are located relative to your car's lights. If you take a lamp that started with a diffuse reflector and make it specular, you might have higher intensity directly in line with the lamp, but at wider angles (like...from the next lane over!), the intensity will be much lower. Also, there's no electroplating that would be suitable as a reflector material. Even the best show chrome is just over 67% reflective even though it looks a mile deep to the naked eye. The aluminum material used for lamp reflectors, whether it's diffuse or specular, is over 98% reflective. But your second suggestion, chrome-in-a-can ("chrome" or "chrome aluminum" spray paint) is an excellent one; that is a very close match for the material originally used on most of our cars' lamp reflectors, and so it's an excellent choice for restoring our lamp reflectors to new efficiency.

But even if we do that, "LED bulbs" don't work. They do not emit the right amount of light in the right directions to allow the lamp's optics to collect and distribute the right amounts of light for safe performance of the lamp as an assembly.
