When the rear door is lifted, the lights are manually or automatically activated and produce a light beam that can easily be viewed by oncoming vehicular traffic. The illuminated light provides an extra margin of safety to personnel attending to a disabled vehicle that has been parked adjacent a road. ## Claims ### Claim 1 A vehicle auxiliary lighting system (VALS) that functions in combination with a vehicle's upward-opening rear door having a lower inner edge, and a vehicle power source, said VALS comprising: a) at least one light having means for being attached to the lower inner edge of the vehicle's rear door, b) means for attaching said at least one light to the rear door, and c) means for activating said at least one light, wherein when the vehicle is disabled the activated said lights produce a beam that is visible to oncoming vehicular traffic which provides an extra margin of safety. ### Claim 2 (depends on 1) The VALS as specified in claim 1 wherein said means for attaching said at least one light to the vehicle's rear door comprises a bracket designed to allow the interface of the bracket to accommodate a particular vehicle rear door. ### Claim 3 (depends on 2) The VALS as, specified in claim 2 wherein said light is further comprised of at least a left light and a right light. ### Claim 4 (depends on 3) The VALS as specified in claim 3 wherein said left and right lights are selected from the group consisting of LEDS, incandescent lights and fluorescent lights. ### Claim 5 (depends on 4) The VALS as specified in claim 4 wherein said LEDS are comprised of a cluster of LEDS. ### Claim 6 (depends on 5) The VALS as specified in claim 5 wherein said cluster of LEDS are selected to provide a red light or an amber light. ### Claim 7 (depends on 1) The VALS as specified in claim 1 wherein the vehicle power source is taken from a constant 12-volt d-c power source. ### Claim 8 (depends on 3) The VALS as specified in claim 3 wherein the vehicle power source is provided from the vehicle's emergency flasher circuit. ### Claim 9 (depends on 3) The VALS as specified in claim 3 wherein said means for activating said lights is provided by a first light activating circuit comprising: a) a first switch (S1) having a contact (A) and a contact (B), wherein the contact (A) is connected to the vehicle power source through a fuse (F1), b) a second switch (S2) having a contact (C) and a contact (D), wherein the contact (C) is connected to the contact (B) on said switch (S1), and the contact (D) is connected to a junction (J1) located between said fuse (F1) and the contact (A) of said switch (S1), c) the third switch (S3) has a contact (E) and a contact (F), wherein the contact (E) is connected to the contact (B) on said switch (S1), and contact (F) is connected to the junction (J1), d) the left light (L1) has a contact (G) and a contact (H), wherein the contact (G) is connected to the contact (B) on the first switch (S1), and the contact (H) is connected to circuit ground, and e) the right light (L2) has a contact (I) and a contact (J), wherein the contact (F) is connected to the contact (B) on the switch (S1), and the contact (J) is connected to circuit ground. ### Claim 10 (depends on 9) The VALS as specified in claim 9 wherein said switch (S1) is located in the vehicle driver's compartment and said switches (S2 and S3) are located adjacent the vehicle's rear door. ### Claim 11 (depends on 3) The VALS as specified in claim 3 wherein said means for activating said lights utilizes is provided by a second light activation circuit comprising: a) the switches (S1-S3) are connected in parallel with each switch having a contact (A) and a contact (B), wherein the contacts (A) are attached to a junction (J1) that is connected to the vehicle power source through a fuse (F1), and the contacts (B) are connected in parallel to a junction (J2), b) a left light (L1) having a contact (G) and a contact (H), wherein the contact (G) is connected to the junction (J2), and c) a right light (L2) having a contact (I) and a contact (J), wherein the contact (I) is connected to the junction (J2), and the contact (J) is connected to circuit ground. ### Claim 12 (depends on 11) The VALS as specified in claim 11 wherein said switches (S1-S3) are comprised of single-pole, single-throw toggle switches or push ON/push OFF switches. ### Claim 13 (depends on 12) The VALS as specified in claim 12 wherein said light (L1,L2) are selected from the group consisting of LED lights, incandescent lights and fluorescent lights. ### Claim 14 (depends on 3) The VALS as specified in claim 3 wherein said means for activating said lights is provided by a third light activation circuit comprising: a) a switch (S1) has a contact (A) and a contact (B), wherein the contact (A) is connected to the vehicle power source through a fuse (F1), b) a switch (S4) has a contact (K) and a contact (L), wherein the contact (K) is connected in series to contact (B) on the switch (S1), c) a left light (L1) has a contact (M) and a contact (N), wherein the contact (M) is connected to contact (L) on the switch (S4), and contact (N) is connected to circuit ground, and d) a right light (L2) has a contact (O) and a contact (P), wherein the contact (O) is connected to contact (M) on the light (L1), and the contact (P) is connected to circuit ground. ### Claim 15 (depends on 14) The VALS as specified in claim 14 wherein said switch (S1) is comprised of single-pole, single-throw toggle switches and switch
