Showing that $\prod_{n=1}^{\infty}\left(1+\frac{1}{F_{2^n+1}L_{2^n+1}}\right)=\frac{3}{\phi^2}$ Infinite product
$F_{n}:=[1,1,2,3,5,8,\cdots]$ and 
$L_{n}:=[1,3,4,7,\cdots]$ 
for $n=1,2,3,\cdots$ respectively.
$\frac{1+\sqrt5}{2}=\phi$
Show that, 
$$\prod_{n=1}^{\infty}\left(1+\frac{1}{F_{2^n+1}L_{2^n+1}}\right)=\frac{3}{\phi^2}$$

We took the idea from this site
Expand the product
(1)
$$\left(1+\frac{1}{F_{3}L_{3}}\right)\cdot\left(1+\frac{1}{F_{5}L_{5}}\right)\cdot\left(1+\frac{1}{F_{9}L_{9}}\right)\cdots=\frac{3}{\phi^2}$$
$F_{n}=\frac{\phi^n-(-\phi)^{-n}}{\sqrt5}$
$L_{n}=\phi^n+(-\phi)^{-n}$
$F_{n}L_{n}=\frac{\phi^{2n}-(-\phi)^{-2n}}{\sqrt5}=F_{2n}$
Rewrite (1)
$$\left(1+\frac{1}{F_{6}}\right)\cdot\left(1+\frac{1}{F_{10}}\right)\cdot\left(1+\frac{1}{F_{18}}\right)\cdots=\frac{3}{\phi^2}$$
Still doesn't help much to get from LHS to RHS. 
We have $F_{2n}=F^2_{n+1}-F^2_{n-1}$ 
I have substituted in, but the formula seem too messy and more complicated.
Can anybody please give a hand?

Hint. One may use the following result, 

$$
\prod_{n=1}^{\infty}\left(1+\frac{F_b}{F_{2^na+b}}\right)=\frac{1-(-1)^b\phi^{-2a-2b}}{1-\phi^{-2a}} \tag1
$$ 

which is proved by J. Sondow here (see proposition 1 on page 3), where $\phi=\dfrac{1+\sqrt5}{2}$ and where $F_{n}:=[1,1,2,3,5,8,\cdots]$  are the Fibonacci numbers.
Applying $(1)$ with $a=2$, $b=2$ using $F_{2^n+1}L_{2^n+1}=F_{2^{n+1}+2}$ gives the announced infinite product.
