As an option that can be cheaper and easier than whole headlight replacement, car led headlight is getting more and more popular. Changing halogen headlight bulbs to LEDs are often seen.
However, 9005 led bulbs are quite a little different from 9005 halogen bulbs. So in this article, we will explain what is 9005 halogen, and the recommended LEDs.
9005 Bulbs on High Beam
9005 type halogen bulbs often use on the high beam side of four-lamp headlights (with some exceptions) where the high beam and low beam are separated.
I think some people say that high beams don’t usually use halogens. Yes. That the reason why we recommend to use LEDs on a high beam as it can take full advantage of LEDs on a high beam. The following explains what the performance required for high beams is, and why LEDs recommend for high beams.
100% light intensity instantly
In the past, HID was a common sense when it came to brightening halogen headlights. Indeed, if you look only at the brightness, LEDs are not comparable to HID. However, due to the structure of HID, it takes several seconds at the earliest after energizing to reach 100% light intensity (brightness). For this reason, it is not suitable for high beams with many ON / OFF operations and is not particularly ideal for operations such as daily passing.
We recommend LEDs for high beam because it can emit 100% of the light instantly when current goes through and emit intense light.
Long-Lasting in City Road
As mentioned above, the high beam often uses for passing, and of course, the number of ON / OFF times tends to be higher than the low beam.
Except for mountain roads and country roads, in Japan, there are plenty of street lights, including streets, so it is possible to ensure sufficient nighttime visibility without using high beams.
Besides, if there are oncoming vehicles, of course, you will have to switch to low beam, and the situation in the city street, where there are no oncoming vehicles is unlikely to last so long. If so, there will inevitably be more opportunities to switch between high and low beams.
The 9005 halogen bulb emits a heating wire called a filament, which is damaged each time the light is turned on and off, making it easier to break. Of course, LEDs may stop lighting due to a failure of the control unit or a defective board, but from the viewpoint of durability, it can say that LEDs are suitable for high beams.
Low beam HID, high beam LED recommended
9005 halogen mainly uses in the high beam headlight. HID uses on the low beam side; it is recommended to use the LED on the high beam side.
The low beam HID a color temperature (Kelvin number) of 4500K, while the high beam 9005 halogen has a color temperature of 3200-3500K. If both are turned on, the color of the high beam and the low beam will differ significantly and look not great,
Therefore, some people replace the 9005 on the high beam side with HID, but as mentioned earlier, HID takes 3-4 seconds to reach 100% brightness, and this is not good for a high beam while giving a signal on passing. So we recommend you to change LEDs on the high beam but keep the HID on the low beam headlight. Because the 9005 LED bulbs can use 4500K led chips and make the light color of the high beam and low beam look almost the same.
