Simple Brake Light Upgrade

I was tossing around the idea of trying to add LED's inside my tail lights to brighten them up a bit and keep the stock CJ look. The stock looking LED lights available are a little pricey so I figured I might as well try a cheaper solution. I figured I would share my results with all of you. So rather than buying LED lights to fit inside my stock CJ brake light housings or buying the full LED replacements, I decided to do a little test with a couple brands of reflective tape.

Here is a picture of the inside of my tail lights. The metal backing plates are a little rusty but I cleaned them up a bit with some sand paper. Notice the extra green wire with the bolt attaching it to the backing plate, that will be my dedicated ground to the lights once they are mounted on the Jeep. I also taped off the license plate opening to keep the lighting as consistent as possible.


Here are the lights with the brake light portion of the bulb illuminated. Notice that the left side is just a little bit brighter so I will keep that as my base lighting and make my modifications to the right side for comparison. You can also see a small sample of the two types of reflective tape I used.


In this picture I used that high temperature foil tape you use on interior home heating duct work. It is fairly reflective and you can see how much brighter the light is with the reflective tape installed. This is fairly similar to aluminum foil.


In this photo I lined the inside of the housing with white reflective tape that you would use on car trailers or to mark your mailbox, ect.,. This particular brand was Avery. You can see how the reflective tape outshines the aluminum tape. Pretty much what I expected to see.


Here is a picture of the reverse lights. Not quite as drastic of a difference as the brake light but brighter none-the-less.


The strips of reflective tape cost me $4.50 for a 2" x 144" worth shipped to my door off of eBay by a seller named graystone101. They are basically scrap pieces to him. It took less than half the tape to line the insides of both fixtures. Not a bad $2.50 upgrade to give my lights a little extra oomph!


Here's one with the flash.


This final picture is with the lens covers installed, stock on the left, reflective tape on the right with the brake light bulbs illuminated.


What do you think?

Thats a great idea! And a cheap no-brainer upgrade for those of us not wanting to shell out the $$ for LED's... Does that white tape have a specific trade name I should google?

I edited my post with that info but the brand I ended up with was Avery. I got 8 strips 2"x18" long for $4.50 shipped to my door off of eBay by a seller named graystone101. I think any white reflective tape would work well. There are a lot of different brands. The 2" wide was perfect.

Thanks for the "Thumbs Up's" guys, I'm now up to 10.

Great idea. My other hobby outside of blowing money on my CJ is blowing money on my aquarium. One of the oldest tricks in the book to increasing light in an aquarium is a simple reflector in your light strip. A reflector can effectively increase your light output by as much as 50% with no extra power consumption. Your tests are living proof.

I've checked with Reflectix in with regard to their easily locally available product FT210 (a lower end tape) and they tell me it's safe to 260 degrees. There are some concerns posted by others from other sites that they're concerned with temperatures within the tail light housing. As for me, I run lights on during darkness and temperatures are cooler here in Oregon so potential danger may well be minimalized. Not to mention the brake and backup lights are used only momentarily. Going to find out what temperature they burn at.

Sharing my idea on other sites? I've wondered why some of my photobucket bandwidth is used on "unknown" sites. I guess that is from people direct linking to my photos, not that I care or that it matters.

I also thought about that but I believe heat is a non-issue. I just had the brake and tail light filaments powered for 10 minutes straight with the cover on the brake light housing and quickly removed it to check the temperatures with my thermal gun. The bulb, or the filament inside of it, gets to about 350-400 degrees but the tape behind it was only around 125 degrees at the hottest point and was only luke warm to the touch, nowhere near being "hot". If the tape was only 125 degrees after 10 minutes I don't think it would ever get hot enough to melt it. I have just the tail light going now and will update with what I find after 30 minutes. I'd be curious to know your results.

So I just just tested this again and found that the outside lens temp was about 215 degrees after 35 minutes with both the tail and brake filaments illuminated. After 45 minutes it was 220 degrees. I removed the lens cover and quickly measured the temps. The bulb filament measured close to 500 degrees but all of the tape around it was maxed around 145 degrees. I could easily touch it with my fingers and it was not hot enough to make me pull away.

Okay, I ran lights on for over an hour (steady state) and the maximum temperature inside the tail lights with the lens on and sealed gets no higher than 150 degrees. Since this Reflectix tape is rated to 260 I think this'll work out fine. I picked this tape up at the local hardware store, and called the maker for its temp ratings.

Great idea! I would have thought that local hardware stores would have had this stuff, but nothing at HD, Lowes, or Ace. I ended up searching for graystone101 and didn't find him on ebay, but a search of "Avery" came up with the tape. Thanks!!
