Lighting system mountable on a surface and including one or more miniature light sources and a multi-part housing including recesses for accepting the light sources and an electrical supply line. The light sources can include light emitting diodes. Separate parts of the housing are mated in a manner to fix the position of the electrical supply line between them, and may be formed with a recess that receives an asymmetrically shaped electrical supply line in only one possible orientation. Similarly, the recesses receiving the light sources may be shaped such that electrical connections with proper polarity are assured. Either or both parts of the housing may be fastened to the surface with adhesives and/or optional holes for receiving pins, nails, screws, bolts or the like. The lighting system is particularly suitable for emergency, railing, landscape and vehicle illumination applications, and may be powered by batteries and renewable energy sources.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION With reference to FIGS.
1 and 2, a non-limiting example of miniature light assemblies 10 used in the inventive lighting bar system of the present invention includes a bright white LED 12, an electric insulated wire having a negative lead 14 connected to the LED 12, a resistor 16 connected to the LED 12, and an electric insulated wire having a positive lead 17 connected to the resistor 16.
The term "wire" as used herein refers to a conductive material having sufficient strength and rigidity to puncture the plastic coatings found on conventional electrical supply lines.
The portion of the wires protruding from the housing are referred to below as `prongs`, and they may include tapered or beveled ends to facilitate the puncturing of the electrical supply line coatings.
The resulting LED connections may be covered by a small, inner piece of shrink-tube 18 after which the complete component assembly 23 is covered by an outer shrink-tube 20, which all together prevent any electrical component from touching housing 22, preferably composed of stainless steel or another sturdy material.
The electrical component assembly 23 is then inserted into the housing 22.
As shown in FIG.
1, one embodiment of the housing 22 comprises of a top portion 26, which includes a flat area 30, an inside chamfered surface 27 and a housing shoulder 33, and a bottom portion 28.
The housing 22 is stepped in such a way that only the dome 24 of the LED fits through the top portion of the housing 26 and the electrical component assembly 23 is contained in the bottom portion of the housing 28.
Once inside the housing 22, the assembly 23 may be surrounded with a commercially available sealant such as epoxy or silicon sealer to prevent any water or moisture from reaching the resistor 16 or connections, but without the sealant being able to reach or coat the LED 12 lens.
Furthermore, the housing 22 is machined so that the top portion of the housing 26 surrounds and protects the LED 12 against damage
