3、 Test Basis:

Test sample light color per ECE R48 chromaticity requirements.

4、 Test Steps:

1、 Light the sample at rated voltage until stable.

2、 Mount the sample on the integrating sphere system, aligned with the baffle.

3、 Start the test and record the results.

4、 Compare measured chromaticity coordinates with the ECE R48 white or amber light zone boundaries.

5、 Determine whether the chromaticity coordinates fall within the specified zone and record the result.

5、 Test Results: see table below

Sample No.	Test Item	Test Requirement	Test Result
1	Light Color	Color coordinates shall meet ECE R48 requirements for white and amber light.	Test passed. Main beam and white background light meet ECE R48 white chromaticity requirements; amber background light meets ECE R48 amber requirements.
