There is an internal tab on the bulb that must be shaved down to fit the plug. The H9 will mount into the Tacoma headlight assembly, however the plug will not fit without modification to the bulb. While a standard H11 is rated at 1000 hours, the H9 is rated at roughly 250 hours. As a high beam bulb, the standard H9 is optimized for output, it will have a much shorter bulb life than a standard H11. H9s are standard bulbs, they are not designed to enhance focus or extend distance projection. Light color temperature and beam pattern will be identical to the stock standard bulb, just significantly brighter. The mild increase in power draw is easily handled by the Tacomas headlight circuit. The standard 55w H11 is 1200 lumens, a 65w H9 will boost that to 2100 lumens. So what are some better halogen options? For the H11 bulb you effectively have either high efficiency performance stock wattage halogens or a high output H9 bulb adapted to an H11 plug.Īn H9 halogen bulb is a significant output upgrade over the standard H11. Inversely, growing the size of the light source causes focus to be diluted, which reduces intensity and reduces distance projection.Īs mentioned the standard or long life bulbs which vehicles come with from the factory are on the low end of the performance spectrum, this does not mean the low output is due to the headlight being a halogen, it is due to the low performing bulb used. Shrinking the light source further causes the focus to increase which provides higher intensity output to project light further without requiring more lumen output from the light source. In order to achieve good performance in a halogen assembly, the light must be omni-directional to utilize the full collective surface of the projector's internal reflector to provide the designed full uniform beam pattern, and the light source must be as small as a halogen wire filament and at the precise center of the housing to have focus, as this is where the headlight assembly is designed to collect and concentrate the light from. Halogen optics are precision engineered to collect and concentrate an omni-directional light source from a very specific position within the center of the assembly and focus it into a hot spot to project the light over distance down road. To better evaluate headlight performance, it helps to have a basic understanding of how headlight halogen optics work. A brighter light source does not necessarily equate to better output. There is much more to performance lighting optics than glare control and lumen output. While it is true the projectors light shield will provide clean cut offs for glare control, that does not mean that all light sources perform the same in the halogen assembly. A common belief is that the light source does not necessarily matter since the projector housing’s internal light shield will control glare, unlike halogen reflectors found on previous generation Tacomas. The 3rd Gen Tacoma is equipped with factory H11 halogen projectors. Your perception that the stock lights are underwhelming is correct, so what can you do about it? So rather than putting good performing bulbs in which have a reduced life span, the OEMs opt for bulbs with the longest life span, at the expense to output. Many consumers would rather have lower performing lights that last a very long time rather than deal with the inconvenience of more frequent bulb changes. Most vehicle manufactures rather not hassle their customers with more frequent bulb changes, which may also negatively affect the perceived quality of their newly purchased vehicle. When you increase the output of a halogen bulb the life decreases. The obvious question to ask is why?! Low performing ‘standard’ or ‘long life’ bulbs last a very long time, but in doing so trade off for lower output. Toyota and nearly all OEMs intentionally put poor performing halogen bulbs in your stock headlights. Stock bulbs leave a lot to be desired, but this poor performance is actually somewhat by design. Lots of pictures at the end too for those that prefer visuals with graph output comparisons.įirst, lets cover why your headlights are terrible.
