18 (3 + 15) SMDS for superior light distribution! Available with 1156 or 1157 type bulb base. Sold Individually.

These 12V DC have 3 forward facing SMD chips and 3 rows of 5 side firing SMDs for a full and brilliant illumination of most taillamp housings. The combination of forward and side firing SMDs provides bright light in over 270 degrees providing a significant improvement over standard LED bulbs. These bulbs can be used for a variety of lighting purposes and are ideal for applications requiring a wide lighting angle such as applications using a lamp housing that redirects the light toward the lens, such as taillamp housings. These bulbs produce ULTRA BRIGHT (Cool) WHITE light when current is applied.

1156 type: 1156 bulbs are designed to operate in applications requiring a single contact on the base of the bulb. These single function bulbs are typically used for reverse lamps and other lighting purposes where dual function is not required. 1156 Base

1157 type: 1157 bulbs are designed to operate in applications requiring two contacts on the base of the bulb. These dual function bulbs will light all the bulbs at half brightness when current is applied to one contact and will reach full brightness when both contacts are provided current. These bulbs are commonly used in dual function locations like tail lamp or marker lamps where the lights operate as running lamps and function as brake lamps when the brakes are applied as well as functioning as turn signals. 1157 Base
