Which Side Should You Install Your HeadlightSticker™?
Proper Placement for Reliable RFID Reads
Choosing the correct side and placement for your HeadlightSticker™ is essential for consistent RFID performance. The location of the RFID reader, the angle of the vehicle, and the shape of the headlight all affect how well the system reads the sticker.
Before installation, identify where the RFID reader antenna is positioned relative to the approaching vehicle.
Step 1: Locate the RFID Reader
Start by determining where the RFID antenna is installed.
Ask yourself:
- Is the reader on the driver’s side or passenger side?
- Is the antenna mounted low near the barrier arm?
- Or is it mounted higher on a pole or overhead structure?
Understanding the antenna location will help determine the best side and position for the sticker.
Step 2: Match the Sticker to the Reader Side
As a general rule, install the HeadlightSticker™ on the same side as the RFID reader.
Examples:
- Reader on the driver’s side → install the sticker on the driver’s side headlight
- Reader on the passenger side → install the sticker on the passenger side headlight
This helps the sticker directly face the antenna for stronger and more reliable reads.
Step 3: Consider Reader Height
Reader height also affects placement.
Lower Mounted Readers
For readers mounted near the barrier arm or ground level, position the sticker on a flatter, more forward-facing area of the headlight.
Higher Mounted Readers
For readers mounted higher on poles or overhead structures, placing the sticker slightly higher on the headlight may improve performance.
Vehicles with larger or more angled headlights may offer several possible mounting locations.
Use the “Rule of Thumb”
The easiest way to confirm placement is by using the HeadlightSticker™ “Rule of Thumb.”
- Place the base of your hand flat against the headlight
- Point your thumb outward
- If your thumb points toward the RFID reader, the placement is likely correct
This quick check helps ensure the sticker faces the antenna for optimal read performance.
Additional Installation Tips
For best results:
- Install the sticker horizontally
- Keep the sticker at least 2 inches away from metal surfaces or trim
- Apply only to the headlight surface
- Do not bend or reposition the sticker once installed
- Clean and dry the surface before application
Because HeadlightSticker™ is designed to be tamper-resistant, removing or repositioning the sticker may damage it.
Final Thoughts
Correct placement plays a major role in RFID system performance. Installing the HeadlightSticker™ on the proper side of the vehicle and ensuring it faces the reader helps maximize read consistency, security, and overall system reliability.
When in doubt, use the Rule of Thumb and align the sticker toward the antenna location.
