## Abstract

A light bar apparatus is disclosed. The light bar apparatus is attached to a vehicle and comprises a plurality of LED lights capable of illuminating in patterns signaled by the vehicle. The light bar is made at least in part of thermosetting polymer material such that the curing of the thermosetting polymer results in a protective layer for the LED lights by shielding the LED lights from excessive vibration from a vehicle in motion.

## Claims

### Claim 1

A lighting apparatus suitable for use as a vehicle light bar comprised of a partially transparent bar shaped enclosure, wherein said bar shaped enclosure encloses a plurality of LED lights, wherein a space between said bar shaped enclosure and said LED lights is filled with a polymer, wherein said polymer is capable of stabilizing said LED lights against vibration generated by a moving vehicle.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein said LED lights are placed in a bar shaped substrate.

### Claim 3 (depends on 1)

The apparatus of claim 1 wherein said space is entirely filled with said polymer.

### Claim 4

The apparatus claim of 1 wherein said polymer is an epoxy polymer.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein said LED lights are capable of lighting up in a specific pattern.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein said LED lights are comprised of different color LED lights.

### Claim 7 (depends on 5)

The apparatus of claim 5 wherein said LED lights are comprised of a plurality of amber LED lights evenly placed between a plurality of red LED lights.

### Claim 8 (depends on 5)

The apparatus of claim 5 wherein said LED lights are comprised of a plurality of white LED lights evenly placed between a plurality of red LED lights.

### Claim 9

A method to supplement an existing vehicle lighting comprising:
a. provide a partially transparent bar shaped enclosure,
b. provide a plurality of LED lights,
c. have said enclosure to enclose said LED lights,
d. filling a space between said enclosure and said LED lights with a polymer wherein said polymer is capable of stabilizing said LED lights against vibration generated by a moving vehicle.

### Claim 10 (depends on 9)

The method of claim 9 wherein said LED lights are placed in a bar shaped substrate.

### Claim 11 (depends on 9)

The method of claim 9 wherein said space is entirely filled with said polymer.

### Claim 12

The method claim of 9 wherein said polymer is an epoxy polymer.

### Claim 13 (depends on 9)

The method of claim 9 wherein said LED lights are capable of lighting up in a specific pattern.

### Claim 14 (depends on 9)

The method of claim 9 wherein said LED lights are comprised of different color LED lights.

### Claim 15 (depends on 14)

The method of claim 14 wherein said LED lights are comprised of a plurality of amber LED lights evenly placed between a plurality of red LED lights.

### Claim 16 (depends on 14)

The method of claim 14 wherein said LED lights are comprised of a plurality of white LED lights evenly placed between a plurality of red LED lights.
