DIY: Headlight Revolution's SuperNova H1 LED V.4 installation 06-08 Forester. Let there be LED light!!
The headlights in the Usdm 06-08 Foresters leave much to be desired. They love to fill up with water, haze over and their light output is okay at best. I dealt with all these issues after purchasing my Forester with poor lighting at night due to the waterlogged and hazed over headlights. To fix these downfalls I replaced my lights with a set of 07-08 Depo sport headlights , I enjoyed the improved looks and lighting (not fogged over) but I was still a bit disappointed given that my STi has HIDs in it.
After doing plenty of research on retrofits, Hid coversions, Jdm headlights, Led bulbs, etc… I still couldn’t decide. After speaking with a friend of mine he told me to check out headlightrevolution.com which is full of plenty info for those interested in what works and why. I decided to give the SuperNova Perfect fit bulbs out but soon found they didn’t fit without a little modification(i.e. file down the led holder). With this I decided to give the SuperNova V.4s, the newest, freshest versions from the Headlight Revolution that will add 2-3x the lumens over the stock halogens.
Before we start, I will preface that I tried my hardest to find a less extreme way to install these. I.e a way to install them a with the ability to strip them out easily if they ended up not being for me. This became the only way to install them without swapping to a much smaller battery or relocating it, as the left headlight cap is only a half inch away from the battery. The cap can easily be modified to allow the wires to pass through and be installed. I did this method thinking I could find a way but it ended up not working. Here are my trials and errors for those interested.
If you are looking to install these just like I did you will need these tools. Link to my headlight removal DIY here. A flat headed screwdriver, a set of Knipex Pliers, multiple styles of clamps, micro fiber towels, Morimoto rubber butyl, oven mitts or heavy duty work gloves, and an oven or a Heat gun.
We will need to release the headlights from the car. These headlights are quite easy to remove from the car. Check my headlight removal DIY guide out here to help you get them removed and started on your project.
Having removed your headlights you will now use your favorite method of loosening up the headlight sealant. I have used the oven method many times before and feel comfortable with it. Here is a link to my baking headlights DIY to help you through it.
With the above steps completed we will now get down to business. The SuperNova bulbs have large heat sinks and fans but will still fit within the factory dust covers. Now the temperature control module is another story, as a large box with the power in and out wiring doesn’t have a chance at fitting within the headlight dust cap or anywhere behind the reflector unit.
Now with the headlights open we find that there is an excellent location underneath the factory low beam reflector housing. We will need to take the temperature control box wiring to the bulb and heat up the wiring spin on securing clamp. Heating up this will allow us to flatten it and pass it through the backside of the reflector housing. Thus giving us the connection to the light bulb. If you do not have a heat gun or hair dryer at your disposal you can flatten it by hand and force it through. Just be careful not to distort it so badly it cannot be reused, heat helps it easily fold over and bounce right back.
Connecting the temp control box and bulb will finish it. I choose to place mine in the most open area behind the reflector housing in case a replacement bulb is necessary. Now we will pull the factory wiring down and use a pair of pliers close the gap on the negative(black wire) female connection. The connectors on the temp box are slightly smaller necessitating a smaller gap to hold on tightly.
Sorting all the connections out we will use a cleaning cloth on the bottom of the headlight surround. This will give us proper adhesion with the 3M doublesided tape, keeping our temp box in place. After placing it, double check your wiring and get everything set up for putting you headlight back together.
The next steps will be closing up the headlight lens and surround back together. You can find that information back in the Baking your headlights post, but I will gloss over it here. Pushing the two pieces together line up all your tabs and set it back in your oven for 250F for 4-5 mins. This allows the butyl to become malleable and you can now put the headlight back together in reverse order of your opening technique.
Having the headlight back together you may now make sure your bulb is clocked properly. The LEDs need to face the sides of the reflector. Which will mean either your LED bulb is facing directly up or directly down for proper reflector housing illumination. Take your headlight out to you vehicle to check your work. Place the headlight back into the vehicle mounting holes and turning the key checking for proper operation.
Congratulations! You have now installed your own SuperNova V.4 LED bulbs and have completed many other tasks. I would recommend checking the beam pattern and correcting as needed. Now you can go out and enjoy your new much brighter headlights!
