Waterproof Strobe LED Grille Light (LED361)

1.Features
-  Work voltage:DC12V / 24V
-  Life  Span: 100,000   
-  G-3 LEDs with 4 bulbs
-   Waterproof and shockproof
- 18 flash patters to pick up and can flash two lightheads together for  synchronization 
-  Perfect  for interior and outer applications  
2. Specifiation

3. Mounting
- Position the unit in its proposed mounting location. Draw a pencil line onto the mounting surface along the top and bottom of the extrusion and a "centerline" centered between the two.
- Two 1/4" holes are required to mount this unit. These holes may be located anywhere along the holes as far apart as possible. ---Mark the hole location onto the mounting surface.
- Using a 1/4" drill bit, drill a hole in each of the areas scribed in the previous step.
- Slide the 2 carriage bolts (installed in the rear of the bar) insert them into the mounting holes.
- Secure the unit by threading the flat washer and elastic stop nut onto each bolt and tightening them firmly.
4.Wiring
See illustration diagram for wiring information
WARNING! All customer-supplied wires that connect to the positive terminal of the battery must be sized to supply at least 125% of the maximum operating current and at the battery to carry the load. DO NOT USE CIRCUIT BREAKER SWITH THIS PRODUCT!

GPS /Glonass/Beidou/Galileo Antenna

1. According to the polarization mode, GPS Antenna can be divided into vertical polarization and circular polarization. With current technology, vertical polarization is not as effective as circular polarization. Therefore, GPS antennas will be circularly polarized except in special cases. 2. GPS antenna is divided into internal antenna and external antenna in the way of placement. The location of the antenna is also important. At this time, the antenna is basically isolated from the interior of the whole machine. EMI is almost not affected. The satellite reception effect is very good. Now, with the trend toward miniaturization, GPS antennas are mostly built in. In this case, the antenna must be higher than all metal components, and the shell must be electroplated and well grounded, away from EMI interference sources, such as CPU, SDRAM, SD card, crystal oscillator, and DC/DC. The use of GPS in cars will become more common. And the car casing, especially the car explosion-proof film can seriously block the GPS signal. An external antenna with magnets, which can be attached to the roof, is essential for onboard GPS. GPS antenna structure
