HEADLAMP INTENSITY MEASUREMENT

M1542001000602

Using a photometer, and following its manufacture’s 
instruction manual, measure the headlamp intensity 
and check to be sure that the limit value is satisfied.

Limit: 30,000 cd or more

NOTE: 

.

1. When measuring the intensity, maintain an 

engine speed of 2,000 r/min, with the battery in 
the charging condition.

2. There may be special local regulations pertaining 

to headlamp intensity, be sure to make any 
adjustments necessary to satisfy such regula-
tions.

3. If an illuminometer is used to make the measure-

ments, convert its values to photometer values by 
using the following formula.
I = Er

2

 Where:

I=intensity (cd)
E=illumination (Iux)
r=distance (m) from headlamps to illuminome-
